Hello,

I am using RcolorBrewer for plotting "similarity scores", starting with pair-wise similarity matrix as input. "similarity scores" range is 0 to1, with 1 meaning 100% similar (see two maps below) http://r.789695.n4.nabble.com/file/n3455953/lingosimilarity.jpg http://r.789695.n4.nabble.com/file/n3455953/bingosimilarity.jpg I would like to have same color key in both the plots. My objective here is to compare two plots visually. By "same color key", I mean, same range - like white for 0 - 0.2, grey for 0.2 - 0.4 and black for 0.8 - 1. Is it possible to make color scale constant in RColorBrewer? If so, please provide me pointers to command !

Thanks in Advance
Chakri
