Hi!
Thanks a lot for your help!
I now do have exactly the plot that I wanted!
(I also realized that I have to use the 'text' command outside of the plot
function; beginners mistake :-)
Cheers,
Nina

That has been my experience and I believe it is documented on the
help(plotmath) page.

Another way would be with the use of the 'atop' function.
substitute( atop(
log[logbase]* ("Ratio L"/"H reverse"),
italic("experiment 2")
), list(logbase=logbase)
)
Returns:
atop(log[2] * ("Ratio L"/"H reverse"), italic("experiment 2"))
