random.snps {snpStats} | R Documentation

## Generate random SnpMatrix

### Description

This function is purely for testing purposes. It can generate SnpMatrix objects which contain more than 2^31-1 elements.

### Usage

    random.snps(nrows, ncols)

### Arguments

`nrows` | The number of rows to be generated
`ncols` | The number of columns to be generated

### Details

All SNPs should be in Hardy-Weinberg equilibrium with an allele frequency of 0.5.

Note that, although the total number of elements can exceed 2^31-1, the numbers of rows and columns are still subject to this limit.

### Examples

    x <- random.snps(100,10)
    col.summary(x)
