I am evaluating SAP Predictive Analytics and have a special focus on R extensions in Expert Analytics.
So I developed a simple R extension to the functionality in an analysis which reads a CSV Dataset object and changes the value of one variable. This R extension is of type Data Preparation and is embedded in a document in Predict view.
Afterwards, I've changed the R extension (another value assignment statement in the R code), stored the extension and used it at another place in the Predictive flow.
So when I take a look at the results of the first embedded R extension, I see that they are computed with the old version of the R source code in the R extension; the second embedded object works with the new program version.
My impression is that I will have a problem when I change a R extension which I am using in several analytical steps in the Predict process in Expert Analytics. With right mouseclick, I can have a look via "Configure Settings" at the component, but this shows only the tabber with the general properties, not the script.
So after changing a R extension, I have to remove all objects in which I used the old version, and to replace them with the newer version of the R extension.
Is this perception correct, or is there another way to change R extensions which are used in the Predict view of Expert Analytics?
