[R] heatmaps and layouts

[Joseph Clark]

With base graphics, you could use par(mfrow) or par(mfcol) to define a simple layout.

I don't know anything about heatmap.2, but I have used image() to make heatmaps and have laid them out with par(mfrow).


Two ways to get a 2 row by 3 column layout, for example:

 

par(mfrow = c(3,2))  # 3 items across each row, 2 rows

par(mfcol = c(2,3))  # 2 items down each column, 3 columns


Start with the par() statement, then each new plot() or image() or whatever will appear in a different position in the layout, as you specify. Again I have no idea if it'll work with heatmap.2.
