[Gabor Grothendieck]

Hi, I need installation instructions. library(pmg) seems not to be enough.
Thanks.

> library(pmg)
Loading pmg()
Loading required package: gWidgets
Loading required package: gWidgetsRGtk2
Loading required package: RGtk2
Error in dyn.load(x, as.logical(local), as.logical(now)) :
        unable to load shared library

  LoadLibrary failure:  The specified procedure could not be found.

Error: package 'RGtk2' could not be loaded

Loading required package: pmggWidgetsRGtk
PMG needs gWidgetsError in assign(x, value, envir = ns, inherits = FALSE) :
        could not find function "gwindow"
In addition: Warning message:
there is no package called 'pmggWidgetsRGtk' in: library(package,
