I have installed community extention, however, no operator is find. A post mentions (http://community.rapidminer.com/t5/RapidMiner-Studio-Forum/discarding-attributes-with-many-missing-v...)
How to use this workflow?
Solved! Go to Solution.
There were no operators for that particular extension if I can remember BUT there was a new Community View. I would go to View > Show Panel > Community (?) and enable it. From there another view pops up in Studio that allows you to login and get those processes.
