So this is a Windows computer. You need Tcl/Tk 8.4.x, not 8.5.0 (which is later than the current R release), and you need to read the rw-FAQ (which is on the Rgui Help menu) Q4.6 and set the variables it tells you about (or compile R from the sources yourself after configuring it to use 8.5.x).

BTW, the message is wrong: R comes with complete Tcl/Tk libraries, just not all third-party addons.

I am Cc:ing the package maintainer to ask him to correct this.

So please will the package author fix the (long-outdated) reference. The canonical URL is

but it may be better to link to
