The select_if verb for loci

An equivalent to dplyr::select_if() that works on the genotype column of a gen_tibble. This function has access to the genotypes (and thus can work on summary statistics to select), but not the names of the loci (look at select_loci() for that feature.

select_loci_if(.data, .sel_logical)

Arguments

.data

a gen_tibble

.sel_logical

a logical vector of length equal to the number of loci, or an expression that will tidy evaluate to such a vector. Only loci for which .sel_logical is TRUE will be selected; NA will be treated as FALSE.

Details

#' Note that the select_loci_if verb does not modify the backing FBM files, but rather it subsets the list of loci to be used stored in the gen_tibble.
