John Kane: I have 120 columns in a data.frame. I have one value in a column named "blaw" that I want to change. How do I find the coordinates?
Roger Koenker: It is the well-known wicked which problem: If you had (grammatically incorrectly) thought "... which I want to change" then you might have been led to type (in another window):
?which
and you would have seen the light. Maybe that() should be an alias for which()?
