R help - Feb 2001 - RWin 1.2.1: Can't access sample datasets, e.g. MASS

I'm pretty sure I'll feel like [more of] an idiot but...
Using Rgui working in a fresh, blank directory.

  [1] "00Index"         "abbey.rda"      
"accdeaths.rda"   "Aids2.rda"
  [5] "Animals.rda"     "anorexia.rda"   
"austres.rda"     "beav1.rda"
   <snip, 'cabbages' IS there>

Same result for any other dataset.

All packages were installed in RW1021/library/<pkg>, some by manual 
download/rinst some by install.packages().

Note that after installation, the library/MASS/data directory contained 
ONLY RData.zip, so I unzipped it; the same for the other data (and R-ex) 
directories in the tree.  Is this new behavior?

There are no .Renviron files on the system and the only .Rprofiles are the 
[#'d out] one in /etc and the original, unmodified 
"mother-of-all-Rprofiles" in /lib/R.  The latter, for some reason,
loads
ctest...

I'm obviously missing something since I didn't go thru any such
gyrations
using R<1.2.1 ?

I get this for MASS only, not for other packages

Yes, RData.zip is deliberate. It saves space (particularly with a FAT16
disk, where little files are very inefficient). In general, if the
installer puts it there you should leave it there.

However, there does seem to be a bug in the packaging of the current MASS
version. The data/filelist file, which is supposed to give the contents of
RData.zip actually has the contents of the data/ directory. 
As a workaround If you edit this file to list the contents of RData.zip
(or just the files you want to load), data() will work.

I encountered the same problem.  However, after I added a command line
option such as -q or --verbose, I could read sample datasets of MASS
package; more specifically, I changed the target box of the Rgui shortcut

from
	C:\R\rw\bin\Rgui.exe
 to
	C:\R\rw\bin\Rgui.exe -q
