[R] Problem in installing and starting Rattle

[kgorahava]

Hello, 

I am trying to install and run Rattle on my Dell Laptop and I have Windows 7
OS.

The following three commands executed successfully :
 install.packages("RGtk2")

install.packages("rattle")

 library(rattle)
Rattle: Graphical interface for data mining using R.
Version 2.5.47 Copyright (c) 2006-2010 Togaware Pty Ltd.
Type 'rattle()' to shake, rattle, and roll your data. 

When I type the below command, I get an error message.

> rattle()
Error in inDL(x, as.logical(local), as.logical(now), ...) :

Learn more about GTK+ at http://www.gtk.org
If the package still does not load, please ensure that GTK+ is installed and
that it is on your PATH environment variable
IN ANY CASE, RESTART R BEFORE TRYING TO LOAD THE PACKAGE AGAIN
Error in as.GType(type) : Cannot convert RGtkBuilder to GType

Error in as.GType(type) : Cannot convert RGtkBuilder to GType

Why do I get this error message ?

Please advice.
