R Script Node

The R Script node allows users to incorporate scripts from the statistical language R into their Construct jobs. This node offers pre-programmed scripts as well as allowing users to include their own scripts in this node.

The R Scripts dropdown list shows the scripts available to be used by the node. This list can be updated through the R Script configuration file which is located at C:\Program Files\Rapid Insight Inc\Veera Construct. Here, users may add new R scripts, modify existing ones or delete scripts altogether.

Once an R script is selected, the input parameters required by the script, along with their data types, are listed in the Parameter Name and Type fields. Users can then designate which of the available data columns will be used to satisfy the requirements.

The output of the R Script node is determined by the script it is running. This will either be a report based upon a single text-based column or a multi-column dataset.

Tip: A convenient way to see script errors is to paste your script into an XML file, then open the script in to Visual Studio. The Visual Studio program will show you if there are errors.
