DEPRECATION

GITHUB

  • The default branch for the repository is now “main” (@zkamvar, #218)

BUG FIX

poppr 2.8.7

CRAN release: 2021-01-06

CRAN MAINTENANCE

  • Links to other packages are now formatted correctly.

poppr 2.8.6

CRAN release: 2020-06-02

BUG FIX

NEW IMPORTS

  • Progress bars are now implemented via the progressr package, which gives the user control over what should be displayed (or not). For example, to get auditory updates instead of a progress bar, you can use the “beepr” package and set progressr::handlers("beepr"). This will play an alert for each step (~50) and a final sound. To suppress all progress bars entirely, you can use progressr::handlers("void"). These progress bars have replaced the utils::txtProgressBar() and dplyr::progress_estimated() bars.

  • shufflepop() is now safer as it now uses a for loop instead of a function with the out-of-scope operator (<<-) (see #205)
  • The MLG class gains a new distenv slot, which will store the environment where the distance function or matrix exists. This is accompanied by an accessor of the same name (see #206).
  • "mlg.filter<-"() replacement methods will no longer search the global environment when evaluating the distance function or matrix (see #206).
  • Tests for mlg.filter() no longer assign objects to the global environment

poppr 2.8.2

CRAN release: 2019-03-11

MISC

poppr 2.8.1

CRAN release: 2018-08-22

BUG FIX

DOCUMENTATION

  • aboot() documentation was updated to add the citation and make clear its purpose and limitations.

MISC

poppr 2.8.0

CRAN release: 2018-05-19

BUG FIX

ALGORITHMIC CHANGE

  • win.ia() may result in slightly different results because of two changes:
    1. The windows will now always start at position one on any given chromosome. This will result in some windows at the beginning of chromosomes having a value of NA if the first variant starts beyond the first window.
    2. Windows are now calculated for each chromosome independently. The previous version first concatenated chromosomes with at least a window-sized gap between the chromosomes, but failed to ensure that the window always started at the beginning of the chromosome. This version fixes that issue. (see https://github.com/grunwaldlab/poppr/issues/179).

DEPRECATION

  • The chromosome_buffer argument for win.ia() has been permanently set to TRUE and deprecated as it is no longer used.

NEW FEATURES

DOCUMENTATION

MISC

poppr 2.7.1

CRAN release: 2018-03-16

MISC

  • Missing documentation for poppr.amova() has been added.
  • Polysat is now listed in imports.

poppr 2.7.0

CRAN release: 2018-03-16

NEW FUNCTIONS

  • make_haplotypes() will split your data into pseudo-haplotypes for use in AMOVA-like analyses. This was a previously internal function, but has been promoted to a user-facing function in this version.

  • as.genambig() will convert genind/genclone objects to Polysat’s “genambig” class. Note that polysat must be installed for this to work.

ALGORITHMIC CHANGE

  • AMOVA will now default to using euclidean distance. This affects all calculations made with within = FALSE or filter = TRUE without a user-supplied distance. This will not have affect those with haploid or diploid data using within = TRUE. The dissimilarity distance is equivalent to a squared euclidean distance for haploid genotypes, but not for any higher ploidy. Those using filter = TRUE without specifying a distance should use a euclidean threshold. This should not be an issue for those who simply want to group isolates with missing data, however as a zero distance is the same for euclidean and dissimilarity. Thanks goes to Patrick Meirmans for alerting me to this error.

NEW FEATURES

  • AMOVA will now calculate within-individual variance for polyploid data.

MISC

  • printing of AMOVA will now better handle any changes in methods from pegas or ade4.

poppr 2.6.1

CRAN release: 2018-01-15

BUG FIX

poppr 2.6.0

CRAN release: 2018-01-08

NEW FUNCTIONS

NEW FEATURES

BUG FIX

DEPENDENCIES

  • The minimum version of igraph has been set to 1.0.0.

MISC

  • The MSN is now plotted last in plot_poppr_msn() so additional legends can be added if necessary.

poppr 2.5.0

CRAN release: 2017-09-11

ALGORITHMIC CHANGE

  • Identified in https://github.com/grunwaldlab/poppr/issues/139, Bruvo’s distance will now consider all possible combinations of ordered alleles in the calculation under the genome addition and loss models for missing data. This will affect those who have polyploid data that contain more than one missing allele at any genotype

    To facilitate comparison, the global option old.bruvo.model, has been created. By default it is set to FALSE, indicating that poppr should use the ordered allele combinations. If the user wants to use the method considering unorderd allele combinations, they can set options(old.bruvo.model = TRUE)

    It must be repeated that this does not affect haploid or diploid comparisons, those that use the infinite alleles model, or those who do not have more than one missing allele at any genotype.

DEPRECATION

  • The warning for a short repeat length vector for Bruvo’s distance is deprecated and will become an error in the future
  • jack.ia is deprecated in favor of resample.ia for clarity.

BUG FIX

MISC

  • The internal plotting function for mlg.table now uses tidy evaluation for dplyr versions > 0.5.0
  • The package reshape2 was removed from imports and replaced with base functions (see https://github.com/grunwaldlab/poppr/issues/144 for details)

NEW IMPORTS

  • Due to the migration to dplyr version 0.7.0, poppr now imports the “!!” operator from the rlang package

poppr 2.4.1

CRAN release: 2017-04-14

BUG FIX

poppr 2.4.0

CRAN release: 2017-04-10

NEW FUNCTIONS

  • jack.ia() will randomly jackknife your sample to a specified n (default is the number of MLG), and calculate the index of association over multiple iterations, giving a distribution of possible values at a given sample size.

NEW FEATURES

  • The function mlg.table() gains new parameters, “color” and “background”. The “color” parameter will create a single barplot with colors representing populations while the “background” parameter will create a background plot showing the abundance of MLGs across populations within the facets.
  • The function win.ia() will now take into consideration chromosomal coordinates when constructing windows. It has additionally acquired a new parameter chromosome_buffer, which allows the user to specify whether or not the window should be limited to within chromosomes.

NOTABLE CHANGES

  • calculation of MLGs for snpclone and genlight objects will be performed via distance-based methods by default. This is in contrast to the previous behavior where individuals were assumed to have unique genotypes. see https://github.com/grunwaldlab/poppr/issues/125 for details.
  • An error will be thrown when attempting to use mlg.crosspop() with an object that has < 2 populations.
  • genotype_curve() will now remove monomorphic loci before calculation by default as these loci misleadingly influence the shape of the curve. This will change the shape of the curve if you have monomorphic loci. This change IS optional via the drop and dropna parameters, but it is not recommended to change these parameters.
  • The calculation for psex() has changed to be more accurate when using method = “multiple”. It also gains the ability to use several values of G, one for each population. Documentation for psex() has also been improved. For details of the change, see https://github.com/grunwaldlab/poppr/issues/101

BUG FIX

MISC

poppr 2.3.0

CRAN release: 2016-11-23

NEW FUNCTIONS

NEW FEATURES

  • There is now a plot parameter for the genotype curve to enable or suppress plotting.
  • Progress bars are now automatically suppressed when running non-interactively. to turn them on when running non-interactively, use options(poppr.debug = TRUE).
  • The progress bar for ia() and poppr() will now show estimated time. This is from dplyr’s progress_estimated().

MISC

  • The hist argument in the ia() is deprecated in favor of plot.
  • The x axis for the genotype_curve() plot is now numeric, allowing you to fit a smoothing function over the points without having to use the hack geom_smooth(aes(group = 1)). This is thanks to Kara Woo for pointing this out on twitter (https://twitter.com/kara_woo/status/783336540407685120).
  • The “show” method for genclone objects now delimits populations and strata by a comma, avoiding confusion with multi-word population names. Thanks to @knausb for the fix in https://github.com/grunwaldlab/poppr/pull/116.
  • Documentation for poppr.amova now contains a note about significance testing with the ade4 function randtest.amova.

  • Startup message now tells you if poppr was compiled with OMP support.

poppr 2.0.0

CRAN release: 2015-07-08

COMPATIBILITY UPDATE

  • poppr has moved to version 2.0 due to adegenet’s recent update. The hierarchy slot introduced in version 1.1 is now being moved to adegenet and renamed strata. For maximum backwards compatibility, all of the hierarchy methods still exist, but they are deprecated and will print a warning with the proper function to use. If you were accessing the hierarchy slot without using the *hierarchy() methods, your code will fail as the hierarchy slot now should only contain a formula object.

NEW DEPENDENCIES

  • poppr now imports elements from dplyr and shiny
  • As required as of 2015-06-29, poppr now explicitly imports: stats, graphics, grDevices, and utils

NEW SUGGESTS

NEW DATA

  • A data set called Pram containing SSR genotypes from the Sudden Oak Death pathogen Phytophthora ramorum (Kamvar et.al., 2015)

NEW MINT FLAVOR

  • refreshing!

NEW FEATURES

  • The default plot for the index of association will now be a single histogram. The user has the option to visualize the standardized index of association (index = "rbarD", default) or the classic index of association (index = "Ia"). If the user uses the function ia with the argument valuereturn = TRUE, then the resulting object can be plotted with the plot function.
  • The function poppr will now plot all populations in a single faceted plot instead of one plot per population.
  • aboot and bruvo.boot will now be able to utilize any function to generate trees (suggested in issue #18).
  • The mlg slot in the genclone object can now optionally hold an MLG class object. This object will contain different definitions of multilocus genotypes, allowing the user to switch between observed, custom, and mlgs defined given a genetic distance threshold.
  • minimum spanning network functions gain the ability to include reticulations using the option include.ties
  • minimum spanning network functions gain the ability to collapse multilocus genotypes by genetic distance with the option threshold.
  • poppr.amova gains the ability to filter multilocus genotypes before calculation.
  • informloci gains the argument “MAF”, which allows the specification of a minor allele frequency cutoff in addition to the cutoff argument. Examples have been updated.
  • aboot can now take genlight objects.
  • poppr.msn and plot_poppr_msn can now take genlight objects.
  • plot_poppr_msn now gives users the option to exclude the legends.
  • Default plotting for mlg.table will no longer produce one plot per population. It will now produce a single ggplot object for all populations. Note that the bars are no longer colored by count.
  • poppr will no longer calculate “Hexp”. Instead, Simpson’s index will be calumniated, but the old index can be retrieved by using (N/(N - 1))*lambda.
  • poppr can now take any statistic that can be calculated from a table of multilocus genotype counts.
  • genind2genalex gains the ability to selectively write different strata.

NEW FUNCTIONS

  • mlg.filter will contract multilocus genotypes given a genetic distance and threshold using one of three algorithms. It can report statistics such as the multilocus genotypes returned, the number of samples within each multilocus genotype, the thresholds at which multilocus genotypes were collapsed, and the genetic distance matrix that represents the new multilocus genotypes.
  • filter_stats will show you graphical output of all the algorithms in mlg.filter.
  • cutoff_predictor will predict the cutoff threshold from mlg.filter.
  • bitwise.dist can efficiently calculate absolute genetic distance for genlight objects.
  • mll “multilocus lineages” is a new replacement for mlg.vector which gains the functionality of selecting the multilocus genotype definition from the mlg slot.
  • nmll counts the number of multilocus lineages
  • mll.custom allows the user to define custom multilocus genotypes.
  • mll.levels allows the user to edit the names of custom multilocus genotypes.
  • poppr_has_parallel will return TRUE if poppr was built with OpenMP parallel library.
  • win.ia calculates windows of {r}_d along genlight chromosomes.
  • samp.ia calculates {r}_d for genlight object by randomly sampling a user-defined number of SNPs.
  • test_replen will test repeat lengths of microsatellite markers for consistency.
  • fix_replen will fix inconsistent repeat lengths for microsatellite markers.
  • diversity_stats returns a matrix containing diversity statistics. Defaults to 4 found in poppr, but can be extended to any statistic that can be calculated on a vector of MLG counts.
  • diversity_boot will bootstrap a MLG matrix over the statistics specified for get_stats. Can also perform rarefaction bootstrap.
  • diversity_ci will calculate and plot confidence intervals for bootstrap resampling of an MLG matrix. This includes rarefaction to the smallest sample size.
  • imsn provides an interactive shiny interface for construction of minimum spanning networks.
  • pair.ia will calculate the index of association for pairs of loci and plot heatmaps.

NEW CLASSES

  • snpclone is an extension of the genlight object that acts very much like genclone. It contains an mlg slot.
  • MLG is an internal class that lives inside the mlg slot of snpclone and genclone objects. It allows the user to easily switch between multilocus genotype definitions.

BUG FIXES

  • I was going too fast to count.

poppr 1.0.5

CRAN release: 2013-12-13

NOTABLE CHANGE

  • The default shuffling algorithm for calculating the index of association has changed from multilocus-style sampling to permutation of alleles. All of the 4 methods are available, but new assignments are as follows: Method 1: permute alleles, Method 2: parametric bootstrap, Method 3: non-parametric bootstrap, Method 4: Multilocus-style sampling. Previously, Multilocus was 1 and the rest followed in the same order. There should be no compatibility issues with this change. Functions affected: ia, poppr shufflepop

BUG FIX

  • Bootstrapping algorithm for bruvo.boot function was not shuffling the repeat lengths for each locus resulting in potentially erroneous bootstrap support values. This has been fixed by implementing an internal S4 class that will allow direct bootstrapping of the data and repeat lengths together.
  • An occasional error, “INTEGER() can only be applied to a ‘integer’, not a ‘NULL’” in bruvo.boot or bruvo.dist fixed.
