R help - Mar 2013 - Superscript followed by number then superscript in text

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,

What did you try?

Anyhow, this works

text(1,1,expression("capacity"~10^3~m^3))

Hello,

Something like this?

plot(1, type = "n")
text(1,1, expression(capacity ~ 10^3 ~ m^3))


Hope this helps,

Hi:

plot(1, 1)
text(1, 0.8, expression("capacity"~10^3~"m"^3))
