It is not the fact that you are using title, but rather (I think) the fact that numbers are handled differently than text in plotmath. You are also unnecessarily using 'paste' and incorrectly including 'sep' argument in plotmath-paste, which does not honor that argument. Regular R-paste != plotmath-paste Quoting the exponents allows textstyle to do its job properly. > plot(1,1, ylab="") > title(ylab = > expression(Respiration~"("*mg~~O[2]~~L^textstyle("-1")~d^textstyle("-1 > ")*')') ,line= 1.5) > [[alternative HTML version deleted]] > You might want to read what the Posting Guide says about HTML posting. > PLEASE do read the posting guide > http://www.R-project.org/posting-guide.html > and provide commented, minimal, self-contained, reproducible code.
