R help - May 2011 - 3 Y axis possible?

Dear list,

We have three time course profiles with very different scales, and we want
to show them in one plot. Is it possible to have three y axis? I guess not,
then what would be other options? something like two 2-y axis plots on a
three dimensional view? Appreciate any comment.

There is nothing to prevent you from putting 3 y-axis on your plot;
might be confusing, but it can be done.  What have you tried and why
do you say "guess not"?  With the use of par(new=TRUE) or by doing
your own scaling, you can use 'axis' to put as many axises as you want
on your graph.

I have a recollection that this issue (well, just for 2 y axes, rather than
3, which is even worse) was discussed in the not too distant past, with
pointers to some good cogent examples of why one ***should not do this***.

However I can't find this discussion; can't think of the appropriate
terms
to search on.

Can anyone remember/point out where this discussion can be found?
