snp.mx-class {GenABEL} | R Documentation

## Class "snp.mx"

### Description

This low-level class contains objects holding large arrays of single nucleotide polymorphism (SNP) genotypes

### Slots

`.Data`:

  object used to store genotypes

### Methods

[

  `signature(x = "snp.mx", i = "ANY", j = "ANY", drop = "ANY")`: subset operations. x[i,j] will select people listed in i and SNPs listed in j.

coerce

  `signature(from = "raw", to = "snp.mx")`: makes an snp.mx object out of raw data

show

  `signature(object = "snp.mx")`: shows the object. Take care that (a) this is internal representation and (b) the objects are usually very large!

### Note
