R Plot (with Image Port)

DeprecatedRSnippet-Node extension for KNIME Workbench version 4.0.0.v202009100739 by Max Planck Institute of Molecular Cell Biology and Genetics (MPI-CBG)

Improved R-graphics Integration for KNIME (better repainting and rescaling). Given an R-script this node will create a single view.
To use other ploting engines like ggplot or lattice you need to export the final plot from within your script using the 'print' command.
Make sure that Rserve is running somewhere, and Knime is accordingly configured (Knime->Preferences). Repainting behavior cam be also configured in the preferences.

Detailed documentation about the scripting integration: MPI-CBG SWEG Wiki
