The companies I (used to) work for use intraday data, sometimes
tick-by-tick data, to backtest trading strategies. In that case speed is
a very important issue and interpreted language environments like R are
slow in comparison to compiled language environments like C/C++. 

Generic environment for quant trading might look like the following: 

time critical computations like backtesting and realtime computing in
C/C++, client/server, GUI etc. in Java, and statistical analysis and
diagnostics, prototyping etc. in Matlab or R or similar.
