cat doesn't work with "bquoted" arguments. At least not with the simple cat(xxx, ccc). Rene

This works but the problem is that I can't define the title ahead before N is defined or changed. The idea is that the title is defined ahead, passed to a function that makes many plots, and N is incremented for each plot. One way to accomplish this would be to have the constant part of the title defined ahead: xxx <- bquote(bold("Plot"~C[max]~"versus CrCl")) Bold is needed because the subscripted text "max" is too light (doesn't seem to follow font changes) but I could leave it out if needed. And then add this to the changing part at the time the plot is made (when the value of N is correct). The changing part is: ccc <- bquote(("Figure"~.(N)) I just don't know how to concatenate both xxx and ccc to create the title.
