SQL Server - running daily jobs with r scipts - r

Question

I was wondering if anybody had any ideas on how to set up a SQL Server Job to run r scripts? Here is what I have so far in terms of the SQL code: I have to extract data out of a database (ETL) and want that data to be aggregated/analyzed by R by a specified date. After that, the database would run automatically. Does anybody have any ideas where the SQL ETL Code (from the database) will go and where the R script procedure would go that would eventually run automatically? Thanks!
DATABASE -> ETL Code from database (generating own dataset) -> Using ONLY that dataset where an R script can then manipulate/transform it.

#description NVARCHAR(512),

SET #description = N'Periodically do something';
SET #owner_login_name = N'login';
SET #database_name = N'DATABASE';
-- Delete job if it already exists:

Sql-server supports running R and python since sql-server 2014. Take a look on this.
Method before sql-server 2014
However if you are using version before 2014, you need to have some other way else. My suggestion is using R to kick start the sql (if you can).
Using library like taskscheduleR. You first make a schedule task of R for computing your data. And then connect to your sql-server by some library like obdc, dbi, etc. to update what you want.
ps. I didn't try this before, but I can make some test if you still have further problem about it.
