I'm pretty sure side =2 will put it on the left hand side. May only work for specific views.

You would also want to assign an empty string to the persp zlab (although that's from memory and I don't have a session running to look up the argument.)

Much thanks David and Peter

I thought about mtext, but didn't try it, as was unsure what the
appropriate 'side' value would be. Any thoughts?

Cheers

Hi All

I'm creating some 3-D plots using the function 'persp', and have a
query regarding the ability to make changes to the label of the
z-axis.

There are two things I would like to do. First, the default setting
places the label a little close to the axis for my liking. Is there
any way of moving the label? I've tried adjustments with 'mgp' in
'par', but without success. The second is to change the direction of
the label. Currently it reads top to bottom, whereas I would like it
to read bottom to top, as per a y-axis on a standard plot. Is there
anyway of doing so?

?mtext   # and use the adj argument

Good idea. This works well if your z-axis is fairly vertical
on you plot.
