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 ?m 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.

plotmath expressions do not support new lines within the expression. From ?plotmath: "Control characters (e.g. \n) are not interpreted in character strings in plotmath, unlike normal plotting." You would need to create each line as a separate expression and use ?mtext, if you wish, to place each line along the axis, using the 'line' argument for placement/spacing. HTH, Marc Schwartz
