I recently installed the R (version 2.0.1) and Bioconductor on my computer. 
I installed the packages in "affy", the affyGui and the limmaGui on my 
computer and they all appear in the Load Package window.
After trying to load the affyGui or the limmaGui packages I receive the 
following message entitled: "Tcl/Tk Extension(s) Not Found"-

limmaGUI requires the Tcl/Tk extensions, BWidget and Tktable.
You must have Tcl/Tk installed on your computer, not just the minimal 
Tcl/Tk installation which comes with R (for Windows).  If you do have 
Tcl/Tk installed, including the extensions (e.g. using the ActiveTcl 
distribution in Windows), make sure that R can find the path to the Tcl 
library, e.g. C:\Tcl\lib (on Windows) or /usr/lib (on Linux/Unix) or 
/sw/lib on Mac OSX.

If you don't know how to set environment variables in Windows, one way to 
make sure that R can find the Tcl/Tk extensions Tktable2.8 and bwidget1.6 
is to copy them from your ActiveTcl installation e.g. in C:\Tcl\lib into 
the Tcl subdirectory of your R installation.
If you do understand how to set environment variables... make sure that you 
have the TCL_LIBRARY environment variable set to the appropriate path, 
e.g.C:\Tcl\lib\tcl8.4 and the MY_TCLTK environment variable set to a 
non-empty string, e.g. "Yes".

If using Windows, be sure to read the R for windows FAQ at 

If your Tcl/Tk extensions still can't be found, try addTclPath("<path to 
Tcl library>"). This could be put in $HOME/.Rprofile

If you need further instructions, please contact your system administrator 
and consider emailing r-help at stat.math.ethz.ch, or browse through the 
R-help archives for a similar question.

The URLs for Tktable and BWidget are:

I searched the mailing list for this specific problem and did not find any 
I also serached the PDF "R for Windows Users" but I could not understand 
the things written about Tcl/Tk.

How can I fix this problem.

Thank you,
