Greetings R Developers,

I've been testing the alpha release of R-3.0.0 and I noticed that the plotting functionality in package tkrplot was not working correctly.
Further diagnosis found the issue to be related to the command '.Tcl("image create Rplot plotname")' from package "tkrplot".

The following example is  taken from here:  http://tkrplot.sourcearchive.com/documentation/0.0.14/tcltkimg_8c_source.html

> library(tkrplot)
> library(tcltk)
> my.tkdev <- function() win.metafile(width=4,height=4)
> my.tkdev()
> plot(1:20)
> .Tcl("image create Rplot fred")
Error in structure(.External(.C_dotTcl, ...), class = "tclObj") :
  [tcl] can't get device image.

This example works fine in R-2.15.3.  I've emailed the package maintainer Luke Tierney but unfortunately he doesn't have the ability to build and test packages on windows.
Can anyone elucidate what tcltk changes have been made in moving to R-3.0.0?

Details of installation are as follows:
