I have installed the recently released version 2.2 of Predictive Analytics. I also performed successfully the R installation using the mechanism inside the expert mode. When being asked I switch to the configuration tab, check the "Enable Open-Source R algorithms" option and verify that the path is correct.
However, when I close the dialog with "Ok" and re-open the "R installation and configuration" screen again, the option "Enable Open-Source R algorithms" is not checked anymore. As a consequence, the R algorithms are not working and stay grayed out.
I also tried it with a manual installation of R following some older guides but this is not working either.
Has anyone any suggestions on what to do to get the R algorithms working?
