[R] 2nd Y-axis text problem

[Sion Roberts]

Dear All,
I'm having problems getting text to appear on a second y axis....because
this can only be done within a plot statement and my attempts to add the
label as text didn't work because the "locator" refers to the plot
area....

Any thoughts greatly appreciated.

Thanks in advance,
Sion
