I'm anything but an expert in R however if I'm labeling a graph axis with a superscript I have tended to use:
> plot (x , y , xlab = expression ("label"^2)) But when you try to have more than one superscript it fails. Assuming you are in a UTF8 location (Western Europe) you could try: > plot (x , y , xlab = expression ("Some label text \UB2 some more label text > \UB2")) That works for me. (B2 is the hex code for UTF-8 character = ^2 and \U is a control sequence that will call that character.) It onlyu works if you are a UTF8 area from what i understand. -- As for rounding - can you not populate a new field using the round command? i.e. something like [metadata][long_4dig] = round([metadata][longitude],4) #I haven't used round before my syntax may be wrong! Then use %s to drop that value in?
