Try this: L <- list(x=1, y=1, ylab=as.expression(bquote(.(format(scaleY), scientific=FALSE)^"-1"))) do.call(plot, L) `bquote` actually doesn't return an object with mode expression but rather of mode call, so sometimes as.expression is needed to coerce the result. The `expression` function isn't really designed to do that. > > Thanks > > Marc > > ______________________________________________ > R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see > https://stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide http://www.R-project.org/posting-guide.html > and provide commented, minimal, self-contained, reproducible code.
