[R] Playwith-problem with loading

[Fencl, Martin]

Helllo,
I am having trouble with running the library Playwith in the R-2.12.0. running under 32bit Windows XP. After calling the library the error message "The procedure entry point gdk_cairo_reset_clip could not be located in the dynamic library libgdk-win32-2.0-0.dll." occurs and the R asks for instaling the GTK+ package. However the instalation of GTK+ thorugh the R fails. I have installed GTK+ by installing GIMP 2.0 version 2.6.10 and set the path of environment variables. But it still does not work. It seems to be that the problem is in gtk2 (which I also installed).
Thank you for any hints!

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
