R Source (Workspace)

KNIME R-Project nodes version 3.6.1.v201808311614 by KNIME AG, Zurich, Switzerland

A node for reading diverse data sources from R into an R Workspace Port. Use this when there are R functions that you want to use to read an exotic file into R but need to branch your workspace in R before bringing it completely into KNIME. The R library "foreign" provides support for some "exotic" data types. Reasons for needing a workspace branch include the generation of multiple visualizations from a single data frame.
