[R] Graphics in BATCH CMD mode
Running R scripts via 'R_exe BATCH CMD inpufile outputfile' works fine with jpeg commands in Windows, but the jpeg commands give an error under Linux because GUI is set to none. Is there a way to use jpeg commands in BATCH CMD in Linux.

[R] binary data
What's the preferred way in R for handling samples with binary data (like chemical fingerprints encoded as hexadecimal strings with 0's and 1's indicating the absence or presence of chemical features) in methods such as clustering and MDS. Do you always have to expand the fingerprint data into individual variables (which can be a few hundreds) or can they be used directly as binary data by some of these methods.
