Hi
Try changing
for(i in 1:250){
jpeg(filename = "graf01.jpg", width = 1024, height = 1024,
to
for(i in 1:250){
jpeg(filename = paste("graf", i, ".jpg", sep=""), width = 1024, height = 1024,
I think that should work, otherwise read up on the paste() function at
http://stat.ethz.ch/R-manual/R-patched/library/base/html/paste.html
Best luck
