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So please will the package author fix the (long-outdated) reference.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

http://cran.r-project.org/bin/windows/base/rw-FAQ.html

but it may be better to link to

http://cran.r-project.org/faqs.html
