[R] Superscript followed by number then superscript in text

[Benjamin Gillespie]

Hi all,

I'm having problems finding the correct format for a command.

I would like to write some text on a plot.

I'm using the following command:

text(x,y,"text here", srt=90)

I would like the text to read:

capacity 10^3 m^3

(with ^ denoting superscript (i.e. each '3' as superscript).

I've tried fiddling around with expression(paste(etc.... to no avail. I receive errors such as: "Error: unexpected numeric constant..."

Anyone had experience with this before? Any suggestions would be great.

Many thanks in advance,
