filter_variants_by_standard_chromosomes {gwasrapidd} | R Documentation |
Filter variants by standard human chromosomes.
Description
This function filters a variants object by standard human chromosomes, i.e.,
1–22, X and Y. In addition to these chromosomes, some variants retrieved
from the GWAS Catalog might be also mapped to non-standard locations, such as
GRC assembly patches, haplotype (HAPs) or pseudo autosomal regions (PARs).
When this happens the main table variants
includes rows for these
cases too. This function removes these.
Usage

Arguments
s4_variants |
