groupedHeatmap {geneplotter} | R Documentation

## Heatmap of a matrix with grouped rows and columns

### Description

The function uses `grid.rect` and `grid.rect` to draw a heatmap with grouped rows and columns.

### Usage

    groupedHeatmap(z, frow, fcol,
      fillcolours = c("#2166ac","#4393c3","#92c5de","#d1e5f0","#fefefe","#fddbc7","#f4a582","#d6604d","#b2182b"),
      bordercolour = "#e0e0e0",
      zlim = range(z, na.rm=TRUE))

### Arguments

`z` | A matrix with row and column names.
`frow` | A `factor` of length `nrow(z)` indicating the row grouping.
`fcol` | A `factor` of length `ncol(z)` indicating the column grouping.
`fillcolours` | A `character` vector of colours from which the colour map is obtained through interpolation.
`bordercolour` | Either a `character` vector of length 1, specifying the border colour of the heatmap tiles, or `NULL` or `NA`, which indicates that the border colour should match the fill colour.
`zlim` | Lower and upper limit of `z` values represented in the colour map.

### Details

The function can be called within other drawing operations from the grid package, e.g. within a viewport.

### Value

The function is called for its side effect, drawing text and rectangles on the current viewport.

      fcol = factor(round(seq_len(ncol(mtcars))/3)))
