Rename Pound Sign
The current student-step rollup export (really, all exports) should be such that I can immediately load it into R (and other packages) without error. Now errors occur, for instance, because there are "#" in the variable names i the student-step rollup. However, it is currently a road-block for helping folks like Bob do analyzes they want to do. --Koedinger 16:30, 16 September 2009 (EDT)
