For the ID list above, it would look like 1 1 2 3 4 6 7 7 8 9 I haven't worked with indexes/data manipulation much in R, so any pointers would be helpful. Many thanks! ~~~~~~~~~~~~~~~~~~~ -Robin Jeffries Dr.P.H.

Hi, On our samba server (3.0.22-SuSE93) we have many printers installed with cups. Most of them are RAW queues to use within Windows. A few of them however, are filtered queues for Linux to use.
