R help - Dec 2013 - labels on right y-axis

OS X
R 3.0.2

Colleagues,

I am displaying two sets of values changing over time; as a result, I have two
y-axes.  I add a label for the right-side Y axis with mtext(side=3, line=1.2,
TEXT).  The text is parallel to the axis -- so far, so good.  However, the text
is rotated counterclockwise from horizontal, whereas I would like it rotated
clockwise.

Neither srt nor las fixes this.  I guess that one convoluted approach would be
to use "text" rather than "mtext".  However, positioning
would be a nuisance and the xpd option would be needed.  Is there any simpler
approach?

I don't see an alternative to text(), but the positioning is not
that difficult:

oldpar <- par(mar=c(5.1, 4.1, 4.1, 4.1))
plot(0)
axis(4)
text(par("usr")[2], mean(par("usr")[3:4]), "TEXT",
     srt=-90, adj=c(.5,-4), xpd=TRUE)
par(oldpar)

Colleagues,

I am displaying two sets of values changing over time; as a
result, I have two y-axes.  I add a label for the right-side Y
axis with mtext(side=3, line=1.2, TEXT).  The text is parallel
to the axis -- so far, so good.  However, the text is rotated
counterclockwise from horizontal, whereas I would like it
rotated clockwise.

Neither srt nor las fixes this.  I guess that one convoluted
approach would be to use "text" rather than "mtext". 
However,
positioning would be a nuisance and the xpd option would be
needed.  Is there any simpler approach?

Hi Dennis,
This sounds like a job for twoord.plot (plotrix). I think I can leave 
the warnings, disclaimers and miscellaneous dissuasion to others.
