[R Heberto Ghezzo, Dr]

hello, i tried to run playwith but :

> library(playwith)
Loading required package: lattice
Loading required package: cairoDevice
Loading required package: gWidgetsRGtk2
Loading required package: gWidgets
Error in inDL(x, as.logical(local), as.logical(now), ...) : 
  unable to load shared object 'H:/R/cran/RGtk2/libs/i386/RGtk2.dll':
  LoadLibrary failure:  The specified procedure could not be found.

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
