[R] Using R for processing computer performance data

Problem solved - The error message I was receiving was due to the way I had
processed the raw sar file into a csv file.  There was a final line with the
average of all disks, and it showed up as a device name "Average".  Since
there was only one row that had this value, the number of rows for each
factor was not equal.  When I removed the line with Average as the device,
it all worked great.

Based on some additional input, using a model with 'boxplot(busy ~
device,data=diskact)' put all the box plots on the same graph.

Thanks to everyone for their help.
