Subject: install.packages with R 2.9.1 under Vista?
In-Reply-To: <4A4AD169.6020406@prodsyse.com>
Spencer,
see ?R_LIBS_USER
once R created "C:\\Users\\sgraves\\Documents/R/win-library/2.9" for
you it is used as a library (since it is the default for R_LIBS_USER if
the latter is unset otherwise). Just delete the whole directory and it
won't be used further on.
Best,
Uwe
