Good description of setup, but the error is more likely
TCL_LIBRARY is not set
This means that your environment variable that
identifies the location of the Tcl/Tk distribution
is not properly set. If you can find your Tcl/Tk
distribution (or install one) and use the
cascade (from windows start button)
Settings/Control Panel/System/Advanced/Environment Variables
to set the variable and then re-start R you
will probably get better results. For a typical
installation C:\Tcl\lib is the correct value.
Newer versions of R1.7.0 for windows will come
with Tcl/Tk bundled in so that this problem should
go away in the relatively near future.
