R+Table to R

This Node Is Deprecated — This node is kept for backwards-compatibility, but the usage in new workflows is no longer recommended. The documentation below might contain more information.

Merges an optional data branch into an R workspace. The data table from the optional in-port is imported into the R workspace as variable R; existing R variables are overwritten.

More details about R:


R Command

R Snippet
The R commands being executed in R.
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.
Flow Variable List
The list contains the flow variables that are currently available at the node input. Double clicking any of the entries will insert the respective identifier at the current cursor position (replacing the selection, if any).

R Binary

R binary path
Path to the local R executable. Note that it is possible to specify the path to the local R executable also in the R section of the KNIME preferences.
Arguments for R binary
Add additional arguments run together with the R binary. The '--vanilla' mode ensures a clean workspace and may cause problems when removed.
Override default
If checked, the specified file is used as R binary. If not checked, the file specified in the KNIME's R preferences is used.
