AlleleShift is an R package to predict and visualize population-level changes in allele frequencies.
The following manuscript provides details on the methods used by the package: Kindt R. 2021 (in prep.) AlleleShift: An R package to predict and visualize population-level changes in allele frequencies in response to climate change.
To install from CRAN, use:
The package can be installed from github via:
library(BiodiversityR) # also loads vegan
library(poppr) # also loads adegenet
library(ggplot2)

library(AlleleShift)The following script is also available from the documentation of the ‘count.model’ function.
Input data ‘Poptri.baseline.env’ and ‘Poptri.future.env’ document bioclimatic conditions for populations in baseline and future climates. ‘Poptri.genind’ is information on allele counts of individuals in the ‘adegenet::genind’ format (note that packages ‘adegenet’ and ‘poppr’ offer various methods of importing data from other applications).
