effectscan {qtl} | R Documentation |
This function is used to plot allelic effect at all markers for selected chromosomes. For backcross, there will be only one line represents the additive effect. For F2, there will be two lines represent additive and dominance effects.
effectscan(cross, pheno.col=1, chr, ylim, gap=25, col=c("black","blue","red"), lty=c(1,2,3), lwd=2, mtick=c("line", "triangle"), main, add.legend=TRUE, ...)
