[R] Text wrap

[Filoche]

Hi everyone.

I have a long label that I would like to split. I found that I could use
"strwrap" for simple text. However, this is not working with this label:

str = expression(paste("< 20 µm phytoplankton ","(cells · ",mL^-1,")"))

plot(...., ylab = strwrap(str,20),...)

I suspect this is because I'm using "expression" for form my label.

I also tried with \n but this is not working either.

Regards,
Phil
