metaheat: Display Data as Heatmap
In MAMA: Meta-Analysis of MicroArray

Description Usage Arguments Author(s) Examples

This function displays a matrix as a heatmap. It is based on function heatmap_2 in the Heatplus package.

1	metaheat(x, Rowv = NA, Colv = NA, distfun = dist, hclustfun = hclust, na.rm = TRUE, do.dendro = c(TRUE, TRUE), legend = 0, legfrac = 8, col = heat.colors(12), r.cex = NULL, c.cex = NULL, ...)

`x`	the numerical data matrix to be displayed
`Rowv`	either a dendrogram or a vector of reordering indexes for the rows, setting to `NA` suppresses re-ordering of rows
`Colv`	either a dendrogram or a vector of reordering indexes for the columns, setting to `NA` suppresses re-ordering of columns
`distfun`	function to compute the distances between rows and columns. Defaults to `dist`
`hclustfun`	function used to cluster rows and columns. Defaults to `hclust`
`na.rm`	logical indicating whther to remove NAs
`do.dendro`	logical vector of length two, indicating (in this order) whether to draw the row and column dendrograms
`legend`	integer between 1 and 4, indicating on which side of the plot the legend should be drawn: 1=bottom, 2=left, 3=above, 4=right
`legfrac`	fraction of the plot that is taken up by the legend; larger values correspond to smaller legends
`col`	the color scheme
`r.cex`	font size for row labels
`c.cex`	font size for column labels
`...`	extra arguments to `image`
