Dears,
do you 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]"
Not exactly clear what you mean by "correct".
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))
?plotmath
This seemed to work fine with main, sub and xlab:
a='speed [m*s^-1]'
plot(1:10,main=parse(text=a))
But maybe you wanted the square-brackets?
a='speed~bgroup("[", 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!
