RSnippet-Node extension for KNIME Workbench version 4.0.0.v202009100739 by Max Planck Institute of Molecular Cell Biology and Genetics (MPI-CBG)
This node executes a snippet/script using an R server (Rserve). The script for R can be selected from a
snippet template repository.
RGG (R GUI Generator)
is used to configure the R code using a graphical user interface in a way that the user does not need to
know scripting in R.
URL of the template file can be set in KNIME->Preferences->KNIME->R-Scripting
The input data table is sent to R as a data frame named 'kIn'. The output data table is pulled from R.
It has to be an R data frame named 'rOut'.
Script Editor:
Copy, cut or paste and R code to the editor and/or select the columns from your data table. If a
template is loaded used the GUI to adapt the script to the input data.
Templates:
Select a snippet template from the template repository (double-click or "Use this template") to use that
script and see the GUI.
The description explains what a snippet does.
Then configure the GUI according to your input data.
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).
