I have R Version 3.5.2, RStudio Version 1.1.463, and Rattle Version 5.2.5. on 2 Windows 10 machines.

After launching Rattle successfully I click on the "Open" button to attempt to open a .rattle file. After clicking the open button I get the following message in the RStudio Console "Error in .RGtkCall("S_gtk_file_chooser_dialog_new_with_backend", title, : Could not parse enum value load" I have re-installed R, R Studio, RGtk2, GTK+ on both machines and get the same error on both machines.

Check which version of RGtk2 is loaded in R if its version 2.20.36 try reverting back to version 2.20.35 that solved my issue.

  • To confirm that there was a change to 2.20.36 that has broken rattle. Currently working on it but a workaround for now is to install 2.20.35. – Graham Williams Mar 24 '19 at 10:50

A change to the RGtk2 package from 2.20.35 to 2.20.36 has resulted in a latent rattle bug being found. For now revert to the previous version of RGtk2.

For Linux:

> install.packages("https://cran.r-project.org/src/contrib/Archive/RGtk2/RGtk2_2.20.35.tar.gz", repos=NULL)

For Windows

> install.packages("https://cran.microsoft.com/snapshot/2019-02-01/bin/windows/contrib/3.6/RGtk2_2.20.35.zip", repos=NULL)

I hope to have a fix for rattle soon.
