Examples

library(qtl2)
iron <- read_cross2(system.file("extdata", "iron.zip", package="qtl2"))
map <- insert_pseudomarkers(iron$gmap, step=1)
probs <- calc_genoprob(iron, map, error_prob=0.002)
pheno <- iron$pheno
covar <- match(iron$covar$sex, c("f", "m")) # make numeric
names(covar) <- rownames(iron$covar)
Xcovar <- get_x_covar(iron)
out <- scan1(probs, pheno, addcovar=covar, Xcovar=Xcovar)

out_rev <- scan_qtl2_to_qtl(out, map)
