[R] Problems installing Tcl/Tk

[Henrik Bengtsson]

Hi, I am not sure what Tcl/Tk you are running, but it is most likely that
[R] does not find the Tcl/Tk software. You have installed a Tcl/Tk software
seperately from [R] have you? I am running ActiveTcl 8.3.2 myself. You can
get it from http://dev.scriptics.com. When you install it, it most likely
installed into

   C:\Program Files\Tcl\

You have to add then C:\Program Files\Tcl\bin\ (**\bin\**) to the system
environment variable PATH. If this is not correctly done I get the following
error:

  > 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

>From within [R] you can update your PATH as below:

  > PATH <- Sys.getenv("PATH")[[1]]
  > PATH2 <- paste(PATH, "C:\\Program Files\\Tcl\\bin\\", sep=";")
  > Sys.putenv(PATH=PATH2)
  > library(tcltk)
  >

and it works. If this works just add

  SET PATH=%PATH%;C:\PROGRA~1\TCL\bin

to C:\AUTOEXEC.BAT and you never have to do the Sys.getenv()/Sys.putenv()
above. If you are running Cygwin with bash you also have to add

  export PATH="$PATH:/c/program files/tcl/bin/"

to your general-bashrc file or similar.

Cheers
