I read the SAP HANA R integration guide (PDF). I am confused with three questions
1. On page 8, it states "avoid iteration". My interpretation is I need to avoid iteration/loop in R code. What consequence if I use loop or even nested loop in R code?
2. SAP HANA can also handle machine learning prediction. What is the difference than to handle machine learning with respect to SAP HANA R integration?
3. In R, plot visualization is easy. Is it possible to code visualization in R and then run in SAP HANA to visualize?
Thanks for your professional advices
