subset.calc_genoprob: Subsetting genotype probabilities
In rqtl/qtl2geno: Treatment of Marker Genotypes for QTL Experiments

Description Usage Arguments Value Examples

Pull out a specified set of individuals and/or chromosomes from the results of calc_genoprob().

## S3 method for class 'calc_genoprob'
subset(x, ind = NULL, chr = NULL, ...)

## S3 method for class 'calc_genoprob'
x[ind = NULL, chr = NULL]

`x`	Genotype probabilities as output from `calc_genoprob()`.
`ind`	A vector of individuals: numeric indices, logical values, or character string IDs
`chr`	A vector of chromosomes: logical values, or character string IDs. Numbers are interpreted as character string IDs.
`...`	Ignored.

The input genotype probabilities, with the selected individuals and/or chromsomes.

grav2 <- read_cross2(system.file("extdata", "grav2.zip", package="qtl2geno"))

pr <- calc_genoprob(grav2)
# keep just individuals 1:5, chromosome 2
prsub <- pr[1:5,2]
# keep just chromosome 2
prsub2 <- pr[,2]
