Just my 2 cents: It might be more useful to split the data part from the 
analysis or trading or whatever part. In the first step, data is 
received and stored in a database. Typically a C/C++ or Java application 
receives data and saves it in a database. In a second step, 
applications, e.g., R, may access the data through the database, either 
access historical data or data in realtime. If well designed, the delay 
of receiving data in realtime through the database instead of a direct 
connection is negligible. And you gain a lot of flexibility with this 
design.

Best regards
