[R] efficiency and "forcing" questions

[david.beede@mail.doc.gov]

Dear R listers --
Thank you for the suggestions from Tony and Prof. Ripley about wintop.  My
understanding is that wintop will monitor CPU and memory usage by process,
so one can tell quickly if an R program is still running or not.  This is
very useful!

You should note however that the MS web page claims that wintop and the
other PowerTools (or PowerKernel) applications should not be installed on
Win 98 machines.  However, a search through Yahoo found users advising
people to disregard the disclaimer on the MS website, although some of the
other PowerTools did cause problems in Win98.  Also, I looked through
www.zdnet.com and found a highly-rated product called TaskInfo v.2.21 that
is free for a thirty day evaluation and only costs $12.  It seems to work
well.  (Note:  this is neither a plug nor an endorsement of the product.)
