[R] Installing R-packages via install.package

[Sven Garbade]

Hi there,

I've successfully installed und updated some contributed R packages (R
version 1.2.2 on Debian Linux, logged in as a normal user), but I'm
wondering about this:

[...]
Could not open /usr/lib/R/doc/html/packages.html at
/usr/lib/R/share/perl/R/Rdlists.pm line 238.
/usr/lib/R/bin/INSTALL: /usr/lib/R/doc/html/search/index.txt: Permission
denied
/usr/lib/R/bin/INSTALL: LibIndex: Permission denied
DONE (MASS)
[...]

Permissions:
$ ls -l /usr/lib/R/library/LibIndex 
-rw-r--r--    1 root     root          410 Feb 27 23:42
/usr/lib/R/library/LibIndex
$ ls -l /usr/lib/R/doc/html/search/index.txt  
-rw-r--r--    1 root     root       124212 Feb 27 23:42
/usr/lib/R/doc/html/search/index.txt

It's possible to load the package with e.g.

> library(MASS)

but all installed contributed packages are not listed

> library()

Packages in library `/usr/lib/R/library':

base		The R base package
ctest		Classical Tests
eda		Exploratory Data Analysis
lqs		Resistant Regression and Covariance Estimation
modreg		Modern Regression: Smoothing and Local Methods
mva		Classical Multivariate Analysis
nls		Nonlinear regression
splines		Regression Spline Functions and Classes
stepfun		Step Functions, including Empirical Distributions
tcltk		Interface to Tcl/Tk
ts		Time series function

The packages are in their correct location (e.g.
/usr/lib/R/library/MASS/). Maybe I have to change the permission of the
above mentioned files manually and reinstall?

Thanks, Sven
