Subject: [Rd] Windows 7 and .libPaths()
Message-ID: <501F97F1.70401@sapo.pt>

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]
Copyright (c) 2009 Microsoft Corporation. Todos os direitos reservados.

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.
