Details

This function may be used for subsetting a RADdata object either immediately after data import, or after additional analysis has been performed. Note however that estimation of allele frequencies, genotype prior probabilities, PCA, etc. are very dependent on what samples are included in the dataset. If those calculations have already been performed, the results will be transferred to the new object but not recalculated.
