Subset data frame for specific SNPs

Subset data frame for specific SNPs only.

subset_snp(df, snp.retain, col.snp = SNPs)

Arguments

df	Data frame containing SNPs.
snp.retain	Character vector. Vector specifying which SNPs to keep. SNPs in snp.retain must match SNPs in col.snp in df.
col.snp	Symbol. Column containing SNPs.

Value

Data frame containing only specified SNPs. If no SNP in snp.retain matches a SNP in col.snp, subset_snp() stops with a warning saying "No SNP in 'snp.retain' matches a SNP in 'col.snp'. Could not filter for SNP.".
