Hi Dan, I've got Rserve and SSEtoRServe running, but Qlik Sense seem not recognize the plugin specific functions such as R.ScriptAggrExStr and therefore the objects (i.e. decisiontree) are empty. Is there any why to troubleshoot / fix the problem?
Qlik Sense will interrogate the plugin what capabilities it has at startup, This means that the SSEtoRServer.exe needs to be running when you start Qlik Sense. If you don't see the expression in the expression editor you may need to restart Qlik Sense.
