Hi Didier,

I tried


and it gave

--14:05:05--  http://cran.r-project.org/src/contrib/PACKAGES
           => `/home/woodstock/hoffmann/R/tmp/fileR4815S31df'

saved [41456/41456]

Warning message: 
No package "0.1" on CRAN. in: download.packages(pkgs, destdir = tmpd,
available = available,  

What am I missing?

There is an underscore ("_") in the name"PTAk_1.1-1". My R will expand this
into "<-" and pervert the 

install.packages(PTAk_1.1-1)  [clip]
Warning messages: 
1: argument `lib' is missing: using /home/woodstock/hoffmann/R/Sources/lib
in: install.packages(PTAk <- 1.1 - 1)

I just disable this feature, but it might be advisable not to use it in
file names too.

Thanks for help.

Kind regards
