Thank you very much for your advice:
try re-installing ggplot2 (either using
the install.packages() command,
results in
install.ggplot
Error: object 'install.ggplot' not found
and
RKWard using Settings->Manage R
packages...->Install / Update / Remove) leads to
Warning: unable to access index for repository /bin/windows/contrib/2.15

Warning: package 'Matrix' in library 'C:/Program Files/RKWard/R/library'

why?
Obviously, updating does not take place....
Any help available?

this means you don't have the package "MASS", which is required by ggplot2. I
don't know, why you lack this package, as in general dependencies get
installed, automatically. You should try re-installing ggplot2 (either using
the install.packages() command, or in RKWard using Settings->Manage R
packages...->Install / Update / Remove). While at it, it may be a good idea to
install any available updates to your packages, too.
It may be worth pointing out, that in the current official version of RKWard
(0.6.0), the RKWard plot history feature is a bit broken in combination with
ggplot2. If that is an essential feature to you, consider using the
development version (http://p.sf.net/rkward/svn).

P.S.: We have a dedicated list rkward-users for this sort of question. In
fact, if you have no particular reason to believe that the problem is related
to RKWard, rather than R, consider asking on r-help (at lists.r-project.org).
