[R] Loading tcltk package fails on WinMe/Cygwin but works with Rgui

I am investigating how well R/tcltk is supported on different system and I
ran into the same problem as Christian Schulz reported on February 7, 2002.

I am using [R] v1.4.1 on WinMe and ActiveTcl 8.3.2. Loading tcltk within
Rgui works just fine and both demo(tkdensity) and demo(tkttest) works as
expected. However, when I start R from my Cygwin terminal dyn.load() fails
to load the library:

% R --vanilla
> library(tcltk)Error in dyn.load(x, as.logical(local), as.logical(now)) :
  unable to load shared library
     "C:/PROGRA~1/R/RW1041/library/tcltk/libs/tcltk.dll":
  LoadLibrary failure:  One of the library files needed to run this
application cannot be found.
Error in library(tcltk) : .First.lib failed

Trying to troubleshoot;
> file <- "C:/PROGRA~1/R/RW1041/library/tcltk/libs/tcltk.dll"
> file.exists(file)
[1] TRUE> dyn.load(file)
gives the same error as above. Suspecting Cygwin paths where interacting
with the Windows paths, I also tried set the working directory to the
directory where the dll is and to load from there
> setwd("C:/PROGRA~1/R/RW1041/library/tcltk/libs/")
> file <- "tcltk.dll"
> file.exists(file)
[1] TRUE> dyn.load(file)
but the same error. As I said, this works fine with Rgui. Any ideas?

Thanks

What `R' is this?  The Windows port only has Rgui and Rterm.

My bet is that you don't have the *Windows* Tcl bin directory in your
*Cygwin* path.   See the rw-FAQ Q3.6.

If by `my Cygwin terminal' you mean the Cygwin bash shell (Cygwin provides
no terminal per se), then with the correct path it does work.  (I have Tcl
installed in c:\R\Tcl and had /R/Tcl/Bin in my bash path.  You can find
out by looking at the environment variable PATH from a running R process.)

I'm getting exactly this on an ancient installation of Win95, but
this time in both Rgui and Rterm. I did more or less the same things,
but got the same result.

more or less the same sentiment, except the Rgui bit. I have had it
working on Win98 and Win2000 installations with no problems. Baffling.

David.

[R] Loading tcltk package fails on WinMe/Cygwin but works with Rgui

...i can only suggest  that  now tcl/tk & win2000 works fine with
this row in  file   /etc/Rprofile
Sys.putenv("TCL_LIBRARY"="c:/develope/Tcl/lib/tcl8.3")

and it is possible to test the entry in R with:
Sys.getenv()


                   TCL_LIBRARY 

"c:/develope/Tcl/lib/tcl8.3" 

regards,christian
