Thanks, I think it is great that the color can be specified as either 3 or 4 columns. It would be nice if the bar plot color arguments also had this flexibility. They currently fail when the color has 4 columns.
Will this bug fix need to wait until the next official release? (I am constrained to using the official releases and not the svn code).

Looks like a bug -- it should accept either 3 or 4 columns. I'll have a chance to look at this further this afternoon.
