Petr, Thank you very much this works. A little more tweaking and I'll have what I need.

Hi. If you read the parameters from a file and put them to a matrix, then all the plots may be produced using a loop like the following. #some parameters p <- matrix(1:18, nrow=3, ncol=6) for (i in 1:nrow(p)) { plot.spdf(p[i, 1], p[i, 2], p[i, 3], p[i, 4], p[i, 5], p[i, 6]) readline("press Enter to continue") } If you use pdf() for sending the graphics to a file, then remove the "readline" command. Hope this helps.
