heatmapPairs {ELMER} | R Documentation

## Heatmap of pairs gene and probes anti-correlated

### Description

Heatmp plot of pairs gene and probes anti-correlated

### Usage

    heatmapPairs(data, group.col, group1, group2, pairs, annotation.col = NULL,
      met.metadata = NULL, exp.metadata = NULL, width = 10, height = 7,
      filename = NULL)

### Arguments

`data` | A MultiAssayExperiment with a DNA methylation SummarizedExperiment (all probes) and a gene Expression SummarizedExperiment.
`group.col` | A column from the sample matrix from the MultiAssayExperiment object. Accessed with colData(mae)
`group1` | A group from group.col. ELMER will run group1 vs group2. That means, if direction is hyper, get probes hypermethylated in group 1 compared to group 2.
`group2` | A group from group.col. ELMER will run group1 vs group2. That means, if direction is hyper, get probes hypermethylated in group 1 compared to group 2.
`pairs` | List of probe and pair genes
`annotation.col` | A vector of columns from the sample matrix from the MultiAssayExperiment object. Accessed with colData(mae) to be added as annotation to the heatmap.
`met.metadata` | A vector of metdatada columns available in the DNA methylation GRanges to should be added to the heatmap.
`exp.metadata` | A vector of metdatada columns available in the Gene expression GRanges to should be added to the heatmap.
`width` | Figure width
`height` | Figure height
`filename` | File names (.pdf) to save the file (i.e. "plot.pdf"). If NULL return plot.

### Value
