Your subject line indicates your confusion. It does not say RGtk2.dll cannot be found (at least, the English version of the message does not say so).

What it means is that RGtk2.dll or one of the DLLs it depends on cannot be found. See the instructions at http://cran.r-project.org/bin/windows/contrib/2.13/@ReadMe

It is Microsoft's error message, not ours.
