[R-sig-hpc] Holtman's levelplot ?

[Red Roo]

Michel,

If you ask your plotting questions over at r-help at r-project.org, Jim Holtman 
will probably address them directly. He is also an instructor for my "Guerrilla 
Data Analysis Techniques" class 
http://www.perfdynamics.com/Classes/Outlines/gdata.html and we just discussed 
this plot 2 weeks ago.
