Open in R

This node opens a local R session and pushes the data table from KNIME into R.
The input data table is sent to R as a data frame named "kIn". If the optional input ports are used then data frames are named "kIn1", "kIn2" and "kIn3".

IMPORTANT :
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)
