[R] dataframe: visualization as tiles(?)

[Itay Furman]

Thanks, but no. In the method that I remember the plot was an 
assortment of oblong(?) tiles, optionally color coded, and 
filling a square region.
According to my recollection it was possilbe to add more 
variables, in which case each tile is broken down further into 
sub-tiles.
