Is it possible insert two or more datasets in the tab "Predict" in SAP Expert Analytics?

Hi All.

I want to create an R extension algorithm that have in input data belonging to different datasets. Datasets have different number of rows and columns so I can not use 'merge' or 'append' functions.

Is there any way to import two datasets in the tab 'Predict'?

Thanks

    Hi Matteo,

    Multiple dataset for analysis (in non-HANA mode) need to be related so they can be merged or appended as you know already. If you want to use an unrelated dataset, you could load it through the R script directly but you'll still have the challenge of merging the output to the rest of the analysis. This will need to be handled by the same R script node that takes the main dataset as input, reads the second one too and outputs the combined result.

    Hope it helps,

    Jayant

      Thank you Jayanta, but how can I read and elaborate a second dataset in a R extension? Which function should I use? Could you give me an example please?

      Thank you very much
