mqmplot.directedqtl: Plot LOD*Effect curves of a multiple-QTL model

Description

Plot the LOD*Effect curve for a genome scan with a multiple-QTL model (the output of mqmscan).

Usage

mqmplot.directedqtl(cross, mqmresult, pheno.col=1, draw = TRUE)

Arguments

cross

An object of class cross. See read.cross for details.

mqmresult

Results from mqmscan of type scanone

pheno.col

From which phenotype in the crossobject are the result calculated

draw

If TRUE, draw the figure.

Value

Returns a scanone object, with added the effectsign calculated internally by the function effect.scan. For more info on the scanone object see: scanone

#Simulated F2 Population

f2cross <- sim.cross(map10,f2qtl,n=100,type="f2")       # Simulate a F2 Cross
f2cross <- fill.geno(f2cross)                           # Fill in missing genotypes
f2result <- mqmscan(f2cross)                    	# Do a MQM scan of the genome
mqmplot.directedqtl(f2cross,f2result)
