This node creates plots using an R server (Rserve). The script for R can be selected from a plot
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 plot window can be rescaled and replotted by double-clicking onto the plot.
The input data table is sent to R as a data frame named "kIn". The plot from R is sent back to Knime as the output.
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.
Select a plot template from the template repository (double-click or "Use this template") to use that script and see the GUI. The description shows you an example plot than can be done using this template. Then configure the GUI according to your input data.
Specify the image dimensions of the plot and the type and location where to save that image.
This node is using R as backend, make sure that Rserve is running somewhere, and Knime is accordingly configured (Knime->Preferences->Knime->R-Scripting). Scripting integration Wiki (R server)
