I am trying to run a basic R script that does text mining for the I Have A Dream speech (see attached). I am trying to have Qlik both run the R script and have Qlik pick up the output for visualization (high frequency words). The SSE plugin is installed and although I have successfully test the R.ScriptEval and R.ScriptAggr functions, I am having difficulty testing this more intermediate level use case. Any guidance will be helpful. Thank you.
if you want to do this is real time as a chart expression (with changes based upon selection), then to get a different granularity of input data to output data then the best way is to use an AGGR function.
But as per the previous answer, if you just need it as a one time thing against the whole data set, then running in the script is a better option.
Use the R.ScriptEvalStr function instead since you are exporting the elapsed time as a string. i found this while trying to use a word cloud based on text loaded from other tables and ran into the same problem and get my wordcloud.png generated via this script:
