In adegenet: Exploratory Analysis of Genetic and Genomic Data

Microsatellites genotypes of 335 chamois (Rupicapra rupicapra) from the Bauges mountains (France)

Description

This data set contains the genotypes of 335 chamois (Rupicapra rupicapra) from the Bauges mountains, in France. No prior clustering about individuals is known. Each genotype is georeferenced. These data also contain a raster map of elevation of the sampling area.

Format

rupica is a genind object with 3 supplementary components inside the @other slot:

xy

a matrix containing the spatial coordinates of the genotypes.

mnt

a raster map of elevation, with the asc format from the adehabitat package.

showBauges

a function to display the map of elevation with an appropriate legend (use showBauges()).
