heatmatrix {caroline} | R Documentation

## Simple Heatmap Plot

### Description

This is a very simplified heatmap function: basically a convienent wrapper around the 'image' function.

### Usage

    heatmatrix(x, values=TRUE, clp=c('bottom','top'), rlp=c('left','right'),
                                 xadj=.02, yadj=.3, ylab.cntr=FALSE, cex=1, cex.axis=1, ...)

### Arguments

`x` | A matrix
`values` | boolean: should the values be plotted over each cell?
`clp` | column label position: either 'bottom' or 'top'.
`rlp` | row label position: either 'right' or 'left'
`xadj` | x-adjust of the row labels
`yadj` | y-adjust of the column labels.
`ylab.cntr` | boolean for justification of row labels.
`cex,` | character expansion factor for values in cells if values == true
`cex.axis` | character expansion factor for axis tick mark labels
`...` | other paramters passed on to image()

### Value

a heatmap plot
