Thanks for your answer. I followed the advice in the readme file and installed

http://ftp.gnome.org/pub/gnome/binaries/win32/gtk+/2.22/gtk+-bundle_2.22.0-20101016_win32.zip

Previously I made sure that all other previously installed GTK+ runtime environments were removed and that the windows PATH reflects the correct path to the "new" GTK+ files. I also made sure I started a new R session before trying 'require(gWidgetsRGtk2)' again. Yet, the same error. More precisely, a dialog box pops up asking me to install GTK+ or not. That's what's confusing me as well: the package's recommendation with respect to the version of an GTK+ runtime environment is somewhat out-of-sync with the advice in the readme, even though it the version is fairly recent (2011-04-30)

Sorry for the german part in the error message, but I wasn't able to get it all to English (tried language = en in Rconsole file, setting up a Renviron.site with LANGUAGE=en, setting Sys.setenv("LANGUAGE"="en") and Sys.setenv("LC_ALL"="en") to no avail; not a good R day today ;-)). I freely translated it for you:

Loading required package: gWidgetsRGtk2
Loading required package: gWidgets
Error in inDL(x, as.logical(local), as.logical(now), ...) :   unable to load shared object
'R:/Apps/R/R-2.13.0/library/RGtk2/libs/i386/RGtk2.dll':   LoadLibrary failure: the specified module could not be found.

Failed to load RGtk2 dynamic library, attempting to install it. Learn more about GTK+ at http://www.gtk.org If the package still does not load, please ensure that GTK+ is installed and that it is on your PATH environment variable IN ANY CASE, RESTART R BEFORE TRYING TO LOAD THE PACKAGE AGAIN Error : .onAttach failed in attachNamespace() for 'gWidgetsRGtk2', details:   call: .Call(name, ..., PACKAGE = PACKAGE)   error: C symbol name "S_gtk_icon_factory_new" not in DLL for package "RGtk2"

Do you have any other idea what I might be doing wrong?

Regards,
Janko
