Subsetting genotype probabilities
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 |
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. |
An object of class "calc_genoprob", like the input, with the selected
individuals and/or chromsomes; see calc_genoprob().
grav2 <- read_cross2(system.file("extdata", "grav2.zip", package="qtl2"))
pr <- calc_genoprob(grav2)
# keep just individuals 1:5, chromosome 2
prsub <- pr[1:5,2]
# keep just chromosome 2
prsub2 <- pr[,2]Please choose more modern alternatives, such as Google Chrome or Mozilla Firefox.
