In the R windows FAQ, item 3.6 (Package TclTk does not work) currently has this
line:
Sys.putenv("TCL_LIBRARY"="c:/Program
Files/Tcl/lib/tcl8.3")
I find that if I execute the following two lines after starting R, I can then do
library(tcltk) and demo(tkdensity) as usual. I do not need to modify my
autoexec.bat this way!
Anyway, using the following two lines in the FAQ might be useful to some
people.
Sys.putenv("TCL_LIBRARY"="c:/Tcl/lib/tcl8.3")
Sys.putenv("PATH"=paste(Sys.getenv("PATH"),
";c:\\tcl\\bin;",
Sys.getenv("R_HOME"),
"\\library\\tcltk\\libs",sep=""))
Humbly (and aplogies for any incorrect terminology)
Kevin Wright

In particular, why do you need .../library/tcltk/libs in the PATH? Both the README and the FAQ already tell you to put the Tcl/Tk DLLs in the your path, so why does the information need to be repeated? Unless something went wrong in your Tcl/Tk installation, they will be in your path, so why put them in a second time? Where is the bug? -- Brian D.

Windows documentation is very unclear about how to get something put into your path. For example, on my system, tcl is not in my path; I "installed" Tcl/Tk by just copying the whole directory from another system. The Sys.putenv commands make it work.

I installed the Tcl/Tk software from www.activestate.com . The installer did not add the Tcl/Tk DLLs to my PATH. (Probably it should, but I don't think the installer provided me with the option of modifying the PATH.) I am creating an R package that will be distributed to people who may not have permission/skill to modify the PATH settings in Windows, so I was excited to figure out that it was possible to set the PATH after starting R. (I will do this in the R package) It was a VERY useful trick for me, which is why I submitted the suggestion. I may be the only person to find the suggestion useful, in which case it wouldn't make sense to modify the FAQ. Kevin> > > > > >Why do you need that?
