getRandomPairs {ELMER} | R Documentation

## Get random pairs

### Description

This function will receive a pair gene probes and will return a random object with the following pattern, if a probe is linked to R1 and L3 genes the random pairs will be a random probes (a distal probe not in the input pairs) also linked to its R1 and L3 gene.

### Usage

    getRandomPairs(pairs, genome = "hg38", met.platform = "450K",
      cores = 1)

### Arguments

`pairs` | A data frame with probe, gene and side information. See example below.
`genome` | Which genome build will be used: hg38 (default) or hg19.
`met.platform` | DNA methyaltion platform to retrieve data from: EPIC or 450K (default)
`cores` | A interger which defines the number of cores to be used in parallel process. Default is 1: no parallel process.

### Value

A data frame with the random linkages
