Windows 7 and .libPaths()

Hello,

I'm having some trouble trying to set the .libPaths() on Windows 7,
R-2.15.0 and R-2.15.1. The environment variables R_LIBS and R_LIBS_USER
are set according to the help page for .libPaths() and the Rprofile.site
file has the default setting, as shown below. R-2.14.1 recognizes the
lib paths but not R-2.15. Is this a bug or am I doing something wrong?

(I've also tried with R-2.12.0 and R-2.13.0 and it works as documented
but I only show here the output for R-2.14.1, R-2.15.0 and R-2.15.1)

First, the Windows settings.

Microsoft Windows [Vers?o 6.1.7601]

C:\Users\Rui>echo %R_LIBS%
C:/PROGRA~1/R/win-library;

C:\Users\Rui>echo %R_LIBS_USER%
C:/PROGRA~1/R/win-library;C:/PROGRA~1/R/win-library/%v;

Then, file Rprofile.site .

# set libPath to win-library
.libPaths(new="C:PROGRA~1/R/win-library")
.libPaths(new=paste("C:PROGRA~1/R/win-library",
paste(R.version$major,as.integer(R.version$minor),sep='.'), sep="/"))

Finally, three R sessions.

Hi,
   A question has come up within a user group about the possibility of
viruses or other malicious code being embedded within any package served
from CRAN. How much checking is done to guard against this?

I do not
expect any kind of response about picking up R code from any other source,
like gitHub. Thanks.

Of course, CRAN cannot guarantee that packages are free of malicious code,
otherwise manual inspection of the code of almost 4000 packages with dozens
of updates and new submissions a day would be necessary.

CRAN does some checks on the precompiled binaries for viruses, but again
cannot give guarantees. Please use the normal precautions with downloaded
executables.


Best,
