Loading tcltk package fails on WinMe/Cygwin but works with Rgui - R-help

Wed, Mar 6, 2002 1:45 PM #

...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"

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
