Hi, I had tried to print plot via postsript in Batch mode (under UNIX) but owing to the help list I found out that was not the right thing to do. However with bitmap() it still doesn't work. I running R in batch mode from a perl script.I don't get any error and get my results but I can't find my plot (mydata.png). Is there a particular tmp directory where it might go ? Do I have to reconfigure a specific R file with path for bitmap ?
