Hi –  Just thought to share about my new passion about "R" , I would like to share my newly experience with R (using R Studio) and its integration with SAP HANA , for the beginners it would be really helpful to follow the below steps and a smooth integration with R studio , enjoy accessing HANA artifacts easily like accessing the tables/view information & Consuming procedures , intention is let the people know the integration & want to share more later on this topic once I am friendly in "R" development fashion –  "still in learning mode" J.

Here are the prerequisites you must have before trying your hands on "R"

HBDCLIENT

HDServer

R-ODBC Package

R Studio

Setup the Data source (in this case SAP HANA DB Server)

Go to Service Marketplace -> Software Downloads -> Support Packages and Patches -> A-Z –> H–> SAP HANA PLATFORM EDITION" –> SAP HANA PLATFORM EDIT. 1.0" –> Entry by Component" –> HANA client

Another step by step procedure to Download the SAP HANA Client –

https://www.stechies.com/install-sap-hana-studio-hana-client-windows-system/#SAP-HANA-Client-Download

Once you have installed HANADBClient in your system then you need to setup data source.

Go to -> Control Panel -> Search for data Source (ODBC) -> Set up data sources (ODBC)

You will get the below popup

On Current tab click on Add one popup will appear for Server/Port information

Enter any data source name/any description for server ad then enter server:port –  if you don’t know the server and port name goto your hana studio (SAP HANA Development perspective) and right click on system then click on properties tab -> Additional properties tab -> Host details. After entering these details click on connect to check if the details are correct or not by entering the username/password if all ok then you get a prompt on connect that connection is successful.

Once you are done with above now download the R Studio (https://www.rstudio.com/ ) and R package (https://cran.r-project.org/ )

Now install both the Components once you are done with R Studio installation download the RODBC package (https://cran.r-project.org/web/packages/RODBC/index.html )  goto your R Studio now & all install r Studio package.

Once we have added the RODBC package now we can check on R studio using library function

Now we can go ahead for accessing our HANA database artifacts, establish the database connection using R commands & then execute sqlQuery function for executing sql commands on R.

I created one table in HANA server for billing docs that I am accessing using "R" below is the sample code.
