R help - May 2002 - Library Tcltk

Dears users,

Thanks for your responses concerning my question of yesterday (about stand-alone
package). Il would like to explore two ways:
-- Tcltk extension,
-- Rweb application.

I have installed ActiveTcl (in F:\Tcl), and I have modified the PATH (in the
autoexec.bat file):

set R_LIBS=F:\R\rw1050\library
set PATH=%PATH%;F:\Tcl\bin
set PATH=%PATH%;F:\Tcl\lib
set PATH=%PATH%;F:\R\rw1050\bin

(I'm working with W2000, but the autoexec.bat is active: I could be sure of
this fact because changes in the autoexec.bat are taken into account, for
example variables for Latex as: set TEX=latex)

As written in the Win-FAQ of R, when I enter Sys.getenv("PATH"), I can
read:
"F:\\Program
Files\\TeXLive\\bin\\win32;C:\\Ghostgum\\gsview;c:\\jdk1.3\\bin;F:\\Tcl\\bin;F:\\Tcl\\lib"
so Tcl seems to be in my PATH...

After that, when I load the Tcltk library, I have this error message:

Error in firstlib(which.lib.loc, package) :
        TCL_LIBRARY is not set
Error in library(tcltk) : .First.lib failed

Is that a problem of the Tcl package installation? What is wrong?

Another question: has anybody some example of things realized with Tcltk and R?

Thank you for your help,
Tristan Lorino

1) You appear to be working on Windows, but failed to say so.

2) Your first question is answered in both the rw-FAQ *and* the README, so
I presume you have not read them (although you quote a non-existent
`Win-FAQ').  Please do so, completely and carefully.

3) Your second question is covered by the demos in package tcltk (and that
is covered in the documentation mentioned above).

Failure to read the rest of the paragraph in rw-FAQ ....
