groupedHeatmap: Heatmap of a matrix with grouped rows and columns
In geneplotter: Graphics related functions for Bioconductor

Description Usage Arguments Details Value Author(s) See Also Examples

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

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

`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.

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

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