This node executes a snippet/script using an R server (Rserve). The script for R can be selected from a
snippet template repository.
RGG (R GUI Generator)
is used to configure the R code using a graphical user interface in a way that the user does not need to
know scripting in R.
URL of the template file can be set in KNIME->Preferences->KNIME->R-Scripting
The input data table is sent to R as a data frame named 'kIn'. The output data table is pulled from R. It has to be an R data frame named 'rOut'.
Copy, cut or paste and R code to the editor and/or select the columns from your data table. If a template is loaded used the GUI to adapt the script to the input data.
Select a snippet template from the template repository (double-click or "Use this template") to use that script and see the GUI. The description explains what a snippet does. Then configure the GUI according to your input data.
This node is using R as back end, make sure that Rserve is running somewhere, and KNIME is accordingly configured (KNIME->Preferences->KNIME->R-Scripting). Scripting integration Wiki (R server)
