Running R from a read-only CD
After reading your suggested page, it does appear that the problem is a security feature that I will have to live with since the CDs will be running on borrowed computers. BUT, if the same R-folder is loaded from a USB Flash Drive, rather than a CD, the help files work just fine. So perhaps there is another way. Any other ideas? Charles Annis, P.E.

Dear R-helpers: I created a folder containing R on a read-only CD and use it by having the R-icon, located on the Windows desktop, point to the CD (R-2.8.1\bin\Rgui.exe) for the "Target," and to a Windows Desktop folder
for
"Start in." This works nicely EXCEPT that the R help() function cannot display
anything,
and presents a screen message saying "This program cannot display
webpage."
This is especially frustrating because on the left of what would be the
help
window is the exhaustive list of all the functions for which R can provide help (but can't display anything). Can anyone provide guidance? Here is the obligatory session information: ....................

This sounds like a Windows security feature, because .CHM is a risky format. There's a page here http://support.microsoft.com/kb/896054 that tells you how to turn it off. Alternatively, you can choose one of the other help formats in R besides CHM help. Duncan Murdoch
