Filter based on provided logical predicates in terms of the variable names in x$snpdf. This function filters both x$snpdf and x$inddf.

Usage

filter_snp(x, expr)

Arguments

x

The output of multidog.

expr

Examples

if (FALSE) {
data("uitdewilligen")
mout <- multidog(refmat = t(uitdewilligen$refmat),
                 sizemat = t(uitdewilligen$sizemat),
                 ploidy = uitdewilligen$ploidy,
                 nc = 2)
