It's a very small firm and He is paying me less than a 1000 dollar (60,000 rs.)to make one; which will include the cloud cost as well. And Shiny server pro is like 10,000 dollar per year.
I'm guessing there are other configurations you can set up without that direct integration, I was just answering your question with the information I had -- which, clearly, didn't include the full picture of your use case.
So in HANA if you host your model as an oData service through creating an .xsodata file, you can consume the models data pretty easily in R/Shiny apps using the jsonlite or curl packages.
Alternatively it’s also possible to use the HANA JDBC driver and the RJDBC package to connect which enables running of SQL, that was the easist way I could work out how to connect it as I couldn’t get the ODBC driver to work.
