Subject: [Rd] tkrplot not working in R 2.13.0
Message-ID: <B37C0A15B8FB3C468B5BC7EBC7DA14CC634738EFF5@LP-EXMBVS10.CO.IHC.COM>

The tkrplot package is not working in version 2.13.0 for windows.  I contacted the maintainer who unfortunately does not have easy access to a windows computer and says that it is working on the other platforms.

I traced the problem down to the line in the .First.lib function:

.Tcl(paste("load", file, "Rplot"))

With file being "C:/Program Files/R/R-2.13.0/library/tkrplot/libs/i386/tkrplot.dll" on my system.  I did check that the file exists and it can even be loaded using dyn.load, but when running the .Tcl command by hand it produces the following error:

Error in structure(.External("dotTcl", ..., PACKAGE = "tcltk"), class = "tclObj") : 
  [tcl] could not find interpreter "Rplot".

It works in previous versions of R, so I am guessing that this is due to some change in R, or the tcl with R 2.13.0, or how tkrplot was compiled under the new R, or possibly something else.

Does anyone else have any insights?
