R グラフィックス

R Graphics (Chapman & Hall/CRC The R Series)

　Amazon.com の方の customer review より．

This is the clearest and most complete explanation of graphics in R that I have seen.
It's in 2 parts (or maybe 2 1/2). The first deals with the 'traditional' graphics system, the second with the Grid graphics system. Also included is an discussion of the Lattice package (that's the 1/2), and various other packages.
My only caveat is that you will probably want to be at least a little familiar with R before using this book. (...)
In my opinion, R is the best program for statistical graphics, and this is the best book on how to get the most out of it.
