Reading .raw file that was previously exported from PLINK - see details. Additional information about SNP mapping is read from .map file.
screen_snps(
rawFile,
mapFile = "",

chunkSize = 100,
verbose = TRUE
)
object of class screeningResult
.
character, name of .raw file.
character, name of .map file.
numeric vector or an object of class phenotypeData
.
numeric, p-value threshold value used for screening.
integer, number of snps that will be processed together. The bigger the chunkSize is, the faster function works but computer might run out of RAM.
if TRUE (default) information about progress is printed.
Exporting data from PLINK
To import data to R, it needs to be exported from
PLINK using the option "--recodeAD"
The PLINK command should therefore look like
plink --file input --recodeAD --out output
.
