Hi Nate,
Welcome to the Quantopian Community!
Our research environment provides the interactive experience you need for prototyping ideas and exploring data. It is based on the IPython Notebook, which has an interface similar to R-studio. Research is in limited beta, but we're granting access to (lucky) users every day, so the wait for access won't be long.
Meanwhile, in the IDE, you can set a breakpoint by clicking on a line number. When your run a backtest that hits the breakpoint, you can add watches to keep track of variables, or you can use the command prompt to explore any data, or execute any command.
happy coding,
fawce
