Dear list members,
I've encountered the following problem with the Rcmdr Help menu in the
development version of R 2.0.0 under Windows XP ("Version 2.0.0 Under
development (unstable) (2004-08-20), ISBN 3-900051-00-3"):
The main Commander window has a (tcltk) Help menu with three items,
"Commander help", "About Rcmdr", and "Introduction to the R Commander",
which, in the development version of the Rcmdr package, call the following
three functions:
helpCommander <- function() help("Commander")
helpAboutCommander <- function() help("aboutRcmdr")
browseManual <- function() {
browseURL(paste(file.path(.path.package(package="Rcmdr")[1], "doc"),
"/Getting-Started-with-the-Rcmdr.pdf", sep=""))
}
(Of course, there are help pages for "Commander" and "aboutRcmdr" in the
Rcmdr package).
These functions are not exported by the Rcmdr package, but as near as I can
tell, that doesn't seem to be the source of the problem.
The third menu item works fine, but the other two [which contain calls to
help()] appear to do nothing. I've tried several variations, including
specifying the package argument to help() and using ? in place of help(),
but to no avail. Curiously, calling, e.g., Rcmdr:::helpCommander() directly
from the R command prompt works just fine.
Unrelated to the above, I've also encountered some MD5 checksum problems
with R 2.0.0 binary packages for Windows installed from CRAN:
------------- output --------------------
files R/car have the wrong MD5 checksums
files R/effects have the wrong MD5 checksums
files R/multcomp have the wrong MD5 checksums
files R/relimp have the wrong MD5 checksums
------------- end ---------------------
Finally, there seems to be a dependency problem with the lmtest package
Windows binary installed via the "Packages -> Install package(s) from CRAN"
menu in the R Console:
------------- output --------------------
> local({a <- CRAN.packages()
+ install.packages(select.list(a[,1],,TRUE), .libPaths()[1], available=a,
dependencies=TRUE)})

Any help would be appreciated, particularly with the problem I'm
experiencing with the Rcmdr Help menu.
Thanks,
John
