tkrplot not working in R 2.13.0

# 
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?
R version 2.13.0 (2011-04-13)

What example are you trying? The code in ?trkplot works for me.

However, it looks to me like that piece of advice in the rw-FAQ about 
no spaces in your path has come back to bite you (I of course do not 
have such spaces).  I think this should be

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

or some such.

Greg,

if he had access (like I do) he'd said it works for him. At least it 
does for me (under Windows Server 2008 and XP) and it also passes the 
CRAN checks under Windows, see e.g.
http://www.r-project.org/nosvn/R.check/r-release-windows-ix86+x86_64/tkrplot-00check.html

You may want to elaborate why you think it does not work and provide us 
with what you typed in R and what the actual error message is.

It looks like the spaces in the path is the problem, when I run the line below with shQuote then everything starts working and all is right with the world again.

Thanks,

Just for fun, see if it also works with

tcl("load", file, "Rplot")

(.Tcl(paste(....)) is just *so* turn of the millennium, and particularly vulnerable to "quoting hell" effects.)

That works as well, I will suggest it to Luke for the package to use.

Thanks,

Thanks -- new version on its way to CRAN.
