I see that I didn't produce the "correct" answer, but perhaps I'm
being thanked for something that was generalizable in that direction.
Better would have ben one of these:
plot(1, ylab= bquote(italic(P) *.(b)*","*~A) )
plot(1, ylab= bquote(paste(italic(P),.(b),",") ~ A) )
In the second instance, paste() is a plotmath expression function,
rather than the character vector function that lives out in the free-
range R.
