Dear Andy,
I've taken the liberty of copying this reply to the r-help and ess-help
lists since my last reply was misleading.
I believe that the problem with tkchooseDirectory() (you can see it by just
calling that function directly) is that it brings up a native Windows
dialog, and it's that kind of tcltk command that I've had trouble with in
ESS/XEmacs under Windows.
Regards,
John

Hi John,
demo(tkfaq) did work for me. Maybe that's the exception...
Thanks!

Dear Andy,
Perhaps it's possible, but I've never been able to get
tcltk to work
properly under ESS/Xemacs on Windows.
Regards,
John

Subject: using tcltk in R under ESS/XEmacs on Windows
Sorry for the cross-post. Not sure where the problem is...
A while back I posted an R function to R-help:
cd - function (dir = tclvalue(tkchooseDirectory()),
saveOld = FALSE,
loadNew = TRUE) {
stopifnot(require(tcltk))
if (saveOld)
save.image(compress = TRUE)
setwd(dir)
rm(list = ls(all = TRUE, envir = .GlobalEnv), envir =
.GlobalEnv)
if (loadNew file.exists(.RData)) {
loaded - load(.RData, envir = .GlobalEnv)
return(invisible(loaded))
}
where the default value for the `dir' argument is to run
the tcltk
directory chooser and get the directory name chosen.
(Thanks to Prof. John Fox for the tcltk part!!) While
this function
works fine under Rgui on Windows, it doesn't work when running R
within ESS (5.2.3) and XEmacs (21.4.13). The directory chooser
never shows up, and dir just gets the empty string. Does anyone
have any idea what could be the problem?
I'd very much appreciate any pointers.
Best,
Andy
