effectscan {qtl}R Documentation

Plot allelic effect across the whole genome

Description

This function is used to plot allelic effect at all markers for selected chromosomes. For backcross, there will be only one line, representing the additive effect. For F2, there will be two lines, representing the additive and dominance effects.

Usage

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,
           ...)

Arguments

cross An object of class cross.
pheno.col Column number in the phenotype matrix which to be drawn in the plot.
chr Chromosome(s) to be drawn in the plot (optional).
ylim y-axis limit.
gap Gap separating chromosomes (in cM).
col Line colors.
lty Line types.
lwd Line widths.
mtick Tick mark type for markers.
main Figure title.
add.legend A logical value to indicate add legend or not.
... Passed to the function plot when it is called.

Details

The function calls effectplot repeatedly for all markers on the selected chromosomes. The results of sim.geno are required for taking account of missing genotype information.

Value

None.

Examples

data(fake.f2)
# allelic effect on whole genome
effectscan(fake.f2, ylim=c(-6,3))
# on first 4 chromosomes, use triangle as marker ticks
effectscan(fake.f2, chr=1:4, ylim=c(-6,3), mtick="triangle")
