In psoerensen/qgg: Statistical Tools for Quantitative Genetic Analyses

Write a subset of data from a BED file

Description

This function reads a BED file and writes a subset of it based on a list of SNP (rsids) identifiers to output BED, BIM, and FAM files.

Usage

writeBED(
  bedRead = NULL,
  bimRead = NULL,
  famRead = NULL,
  bedWrite = NULL,
  bimWrite = NULL,
  famWrite = NULL,
  rsids = NULL,
  endian = .Platform$endian,
  useBytes = TRUE
)

Arguments

bedRead	The full path to the input BED file to read.
bimRead	The full path to the input BIM file to read.
famRead	The full path to the input FAM file to read.
bedWrite	The full path to the output BED file to write.
bimWrite	The full path to the output BIM file to write.
famWrite	The full path to the output FAM file to write.
rsids	A character vector containing SNP rsids to select from the BIM file.

Value

No return value. Files are written to the specified output paths.
