Bora Beran - thoughts too? I am thinking R is the best option here
Yes, I’ve toyed with that… it works but is a kludge. Since the Tableau mechanism to tie into services, can only return one value per cell, I have to make that call to the R server at least 4 times to get, lower C.I., upper C.I. and forecast mean and residuals. Plus having an R server stood up just for the purpose of running RServe is not a great ‘production’ solution in my opinion. Dunno… jury is still out here. It would be great if Tableau could adopt the R integration that PowerBI has… as a datasource, as a transformation or as a visual output. That integration with the visual power and ease of Tableau would be a fantastic solution. Thanks for contributing Patrick!
