plotVarExplained {BioMM} | R Documentation

## Plot data summary statistics

### Description

Plot data summary statistics in terms of the proportion of variance explained.

### Usage

    plotVarExplained(data, posF = TRUE, stratify = c("gene", "pathway",
      "chromosome"), core = MulticoreParam(), fileName = NULL)

### Arguments

`data` | The input dataset (either data.frame or matrix). Rows are the samples, columns are the probes/genes, except that the first column is the label (the outcome).
`posF` | A logical value indicating if only positively outcome-associated features should be used. (Default: TRUE)
`stratify` | A string. The applied stratification method to generate `blocklist`. Valid options are c('gene', 'pathway', 'chromosome').
`core` | The number of cores used for computation. (Default: 1)
`fileName` | The file name specified for the plot. If it is not NULL, then the plot will be generated. The plot will project the data on the first two components. (Default: 'R2explained.png')

### Value

An output image file with '.png' format.
