If you just want the title, look at ?mtext.

Apologies for the private mail, Nabble has not yet updated the thread so I 
can write another post in it. I think I have confused things. I don't mean 
the labels are incorrect. They are fine. What I am referring to is a title 
for the secondary axis, which is currently entitled as "c(-100,200)". 
Obviously this isn't very useful.

I will put some reproducible code on the post when it updates.
