The first thing to check with this stuff is that you have a valid R
expression. The first two are not valid since for one thing a % by
itself is not possible in R syntax - also, a "*" immediately after a
left parenthesis is surely wrong. The third one results from pasting
an expression and a character string, which gives a character string,
and no math plotting.

Did you mean

expression(S/S[MSY] * "%")
