Hello,
This is Elaine.
I am drawing a plot with x-axis label with "km square" as the unit.
Now I want to print km square in the form of km2 and output "2" as the
uppercase.
Please kindly help suggest command to show the uppercase.
When you say "as [the] uppercase" I *think* you mean "as a
superscript". Assuming that I am correct in my supposition,
you can achieve what you want via the syntax shown in the
following example:
plot(1:10,ylab="y",xlab=expression(plain(km)^2))
For details on how you do this sort of thing in general see:
?plotmath
Be warned --- it's tricky! I find that I always need to experiment
quite a lot before I get it right. Experimentation is cheap, but.
