Subsetting imputed genotypes
Pull out a specified set of individuals and/or chromosomes from
the results of sim_geno().
## S3 method for class 'sim_geno' subset(x, ind = NULL, chr = NULL, ...) ## S3 method for class 'sim_geno' x[ind = NULL, chr = NULL]
x |
Imputed genotypes 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 "sim_geno", like the input
with the selected individuals and/or chromsomes; see sim_geno().
grav2 <- read_cross2(system.file("extdata", "grav2.zip", package="qtl2"))
dr <- sim_geno(grav2, n_draws=4)
# keep just individuals 1:5, chromosome 2
drsub <- dr[1:5,2]
# keep just chromosome 2
drsub2 <- dr[,2]Please choose more modern alternatives, such as Google Chrome or Mozilla Firefox.
