power.plot: Comparison of power of qtl detection.

In pheno2geno: High-Throughput Generation of Genetic Markers and Maps from Molecular Phenotypes for Crosses Between Inbred Strains

Description

Plots maximal values of QTL peak measured on the same phenotypes in two crosses.

Usage

  power.plot(cross1,cross2,scores,qtlThr=5,nPheno=500,verbose=FALSE,...)

Arguments

cross1	An object of class cross. See read.cross for details.
cross2	An object of class cross. See read.cross for details.
scores	An object of class scores (result of running of this function). This allows for not recalculating QTL scores everytime user wants to plot them.
qtlThr	Threshold for assessing the significance of the QTL peak.
nPheno	Nr of phenotypes that will be scanned for QTLs. Phenotypes are selected randomly.
verbose	Be verbose.
...	Arguments passed to scanone function (see scanone).

Details

Plots maximal values of QTL peak measured on the same phenotypes in two crosses. This give a good comparison of power to detect the QTLs between crosses, if the number of phenotypes scanned is large enough.

Value

An object of class scores containing all the QTL scores calculated during the run of this function. This can be plugged back into the function to avoid unnecessary recalculation of the scores.
