...u know whether it is possible to include any square parantheses (brackets) in an expression to use it as an axis label? e.g. I would like to have a label like (with the sub and superscripts correct): "speed [m s^-1]" I know how to combine an expression with text via paste, but as I run soimething like: a='m*s^{-1}' plot(1:10,main=parse(text=a)) I found now way of doing this. I use the parse thing as I have all these units stored as strings that represent expressions. Cheers for any help! Jannis
