R: Error when running rattle() - "Invalid root element: 'requires'"

Question

I installed rattle package and associated GTK+ library for windows (I work in Windows 7, R version 3.4.0). No issues installing them. The library(rattle) command runs ok (no error messages), however when I run rattle() I got this error:

Error in method(obj, ...) : Invalid root element: 'requires'

Any recommendation on how to fix it?

Answer 1

Below are the known compatible version which will definetly work. 1. Try to downgrad your R version to 3.3.2. 2. Download RGtk2 version with 2.20.33 and manually install it. 3. Install rattle version as 4.1

Answer 2

The development version of rattle (currently 5.0.18) now works with the latest version of RGtk2 (2.20.33) and the earlier version (2.20.31) under recent versions of R.

install.packages("devtools")

devtools::install_bitbucket("kayontoga/rattle")

Hope that helps.
