oops, there was a little problem with an automated text replacement in
my last post. m^3 should be read as m ^ 3 (without white space).
or, using curly brackets for safety, try
plot(1,ylab=expression("Soil moisture
content"~~bgroup("(",m^{3}*m^{-3},")")))

Thanks Eik, I just tried the following:
plot(sm~wf, type="n", xlab="Levels of droughting gradient", ylab=expression("Soil moisture
content"~~bgroup("(",m^3*m^{-3},")"))), bty="l", font.main="2", pch=16, las=1, cex.lab="1.13")
and got error messages, saying 'unexpected string constant' - have I missed
something?

Hi Sarah,
expression works well, but you have to use it as function.
plot(1,ylab=expression("Soil moisture content
"~~bgroup("(",m^3*m^{-3},")")))
see
?plotmath
for further examples

Hi All,
I am trying to lable the y-axis on my scatterplot with the following:
"Soil moisture content (m3m-3)"
I am using the following coding for plotting the graph:
plot(soilmoisture~gradientlevel, xlab="Levels of droughting gradient", ylab="Soil moisture content (m3m-3)",
bty="l", font.main="2", pch=16, las=1, cex.lab="1.13")
I have tried to incorporate 'expression' into this coding for the ylab as
follows (with also a few variations):
plot(soilmoisture~gradientlevel, xlab="Levels of droughting gradient", ylab=expression"Soil moisture content
(m^3m^-3)", bty="l", font.main="2", pch=16, las=1, cex.lab="1.13")
...but this isn't working and the second m never seems to come up wth
superscript 3 after it. I'm guessing I have tried to incorporate 'expression'
too simply!
Would someone please advise me as to the coding for this?
Many thanks
Sarah
