Kepler

R-script development within an RExpression actor can get pretty tedious. For example, when you add a line of code and want to test its effects, you push the RExpression actor "commit" button and this closes the RExpression actor. You can then run the workflow. Then, to make the next small change, you re-open the RExpression actor, alter the code, push "commit", etc. I have repeated this procedure 741 times in a single day (yes, I counted :). It would be REALLY nice if, when the text within the R-code window of the RExpression actor changed, the "submit" button would become activated (i.e., not grayed out). Then, when an analyist has added the next bit of code, they can just push submit and "run" the workflow. In other words, "submit" does not close the RExpression actor, but does make R-code changes visible to the workflow. Is this possible with Kepler?
