R To R

Takes the R workspace from the input port and modifies it according to the entered R script. The node outputs an R workspace containing the updated variables.

More details about R:


R Snippet

R Script
The code being executed in R. Code may be executed in full or in part using the Evaluate Script and Evaluate Selection options, respectively. Output is printed to the console.
Column List
The list contains the column that are available in the input table. Double click any of the column names to insert the respective field in the expression editor. It will replace your current selection or simply insert at the current caret position.

Overwrite default path to R home
Check this option to select a path to the home of a R installation that is different from the path configured on the R preference page. The path must point to the root folder of the R installation tree. You can either specify the path directly or use the R installation in a conda environment. The conda environment can be specified using a conda environment flow variable from e.g. a “Conda Environment Propagation” node.
