This was an SAP webcast last week with some good question & answer – see below:
SAP Predictive Analytics: Leverage Domain Expertise with R Extensions Q&A
Q: Is Predictive Analytics in Cloud for Analytics?
A: not yet. Wait for a few weeks and you’ll see some announcements
Q: What about algorithms called HANA R-xyz”? Do they automatically come with HANA as well?
A: Yes, that’s right. “HANA R” components contain R code execute server-side. Hence you must have an R-Server added to your HANA environment.
Q: Are all the algortihms also available if you do not connect to a HANA but use data from an Excel input or BW?
A: Yes they are.
Q: Can I consume the output of an R function with design studio or SAP dashboards?
A: The process flow in Expert Mode can write the output into a HANA table. Design Studio, Lumiry, etc could pick up the data there to share with a broader audience
Q: Are users allowed to load any R library needed in an R component? Any security mechanism?
A: The R extensions can load any library installed on the R-Server next to HANA. Typically the library install on that server (at least in production) needs to be done by an Administrator
Q: Can we integrate the custom charts coming from the R Components into the Visualize, Compose & Share rooms ?
A: the charts from r extensions are currently restricted to the Predict tab. This feature has been requested by others and submitted here. Please add your vote
Q: what’s the value of running the R script thru PA vs just running in R?
A: You can create new components for less experience users, making sure they dont have to code R themselves. They can easily configure the logic through ie through dropdowns. Also, with HANA the code is executed server side (ie no traffic to your client).
Q: Can SAP Predictive Analytics read data directly from SAP HANA or BW or BPC or ECC?
A: Yes, SAP PA can read from HANA, BW, ECC and lots other sources, for instance BusinessObjects universes or Hadoop
Q: Can it write back to any of those systems?
A: PA can write to HANA, flat files and through JDBC to databases
Q: Can you post links to the documentation?
A: all Analytics documentation is on http://help.sap.com/analytics
