Hi Chamila,

The SAS package (SAS9.4) has that facility with little programming. I have not much exposed to sentiment analysis but SAS having that facility.

Hi Chandana, thanks very much for the reply and the links. I've never used SAS, looks like it is worth learning. Thanks again.

Hi Dr. Katselidis, thank you so much for these resources. I didn't know about sentR. I'm going to try all three of these options and see it works. I appreciate the help.
