First at all thanks a lot for the reply and sorry for the incomplete
informations:
OS: Windows XP, SP2, version 2002
The computer is connected to a network with several data servers
(uni). R is installed locally at the default location. I have an user
and an admin account for this computer. As the problem I have seams
not to be common a short history of what I have done so far (without
success):

1. Installed the package using the admin login at the default location

2. Installed the package from the usr account into R_LIBS_USER (C:\RLIBS)

3. I have tried to dig into the error using options(error=recover). I
did not get to far but
file == "C:/RLIBS/maps/data/worldMapEnv.r".
I had a look at the zip file in "C:/RLIBS/maps/data". It contains
worldMapEnv.r (but as I do not really understand the package
architecture I can not interpret its single line contents (worldMapEnv
<- "R_MAP_DATA_DIR"))

4. If I am trying to run any thing like example(lm) I am getting the
same error in zip.file.extract (but so far i did not care)

5. I tried to call R from the DOS box using R --vanilla but that did
not work either

6. I reinstalled maps form several CRAN mirrors

7. I tried to run maps on my private computer at home and that did
work... which increases the confusion.

again thanks for any help!
