sex.predict {DOQTL} | R Documentation

## 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.

### Examples

      ## Not run:
        data(snps)
        sex.predict(x, y, sex = rep(F, ncol(x)))
