[R] irregual space plot

[Jason Fisher]

Hello everyone...

I was hoping an R wizard could help me out with this one.  My current R 
programming endeavors require that I generate plots of groundwater state 
variables (e.g. pressure fields, contaminate plumes, etc.) in a 2-D slice of 
a 3-D system.  While the functions contour() and filled.contour() are close 
to what I’m looking for, they unfortunately lack in their inability to deal 
with irregular boundaries (non-rectangular systems).  The irregular systems 
I’m working with are made up of finite elements (each 2-D element 
constructed from 3 or 4 nodes) where linear basis functions describe every 
point (x,y) in the element.  I believe I could deal with my plotting dilemma 
if I had a function very similar to “.Internal(filledcontour())”.  A 
function, which would allow me to specify contours or colors between 
contours within an element.  If someone could give me a hand on this project 
or point me towards helpful resources, it would be greatly appreciated.

Regards,

Jason

PS:  If any additional information is needed, please ask.
