sex.predict: Determine the sex of each sample

In dmgatti/DOQTL: Genotyping and QTL Mapping in DO Mice

Determine the sex of each sample

Description

This function uses the mean X and Y chromosome intensities to predict the sex of each sample. Linear discriminant analysis from the MASS package is used.

Usage

  sex.predict(x, y, snps, plot = FALSE)

Arguments

x	Numeric matrix, num.samples x num.snps, containing X intensities for all samples.
y	Numeric matrix, num.samples x num.snps, containing Y intensities for all samples.
snps	Data.frame containing SNP IDs, chromosomes, Mb and cM locations in columns 1 through 4, respectively.
plot	Boolean that will create a plot of mean X and Y Chr intensities if TRUE. Default = FALSEALSE.

Value

Character vector with sex assignments.
