Re: [R] 'persp' query
Certainly, you will want to set zlab=. mtext() is quite flexible; you can control distance to the axis with line=1.5, say. But remember that mtext() is a 2-dim graphics function - it looks at your plot as a 2-d plot. That's why I made the comment about your z-axis having to be fairly close to vertical on the page. Try the first example in ?persp and follow the call with mtext(my z label, side=2). Because of the tilt of the z-axis, this looks a bit strange (to me). -Peter Ehlers Geoffrey William Heard wrote: Much thanks David and Peter I thought about mtext, but didn't try it, as was unsure what the appropriate 'side' value would be.

[R] 'persp' query
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?

Re: [R] 'persp' query
Geoff, One way (the only way without modifying source code?) to satisfy your first wish is to insert a newline before your label as in zlab = \nMy z-text. I don't know of an answer for your second wish other than using the single letter Z as your label :) -Peter Ehlers Geoffrey William Heard wrote: 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.

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?

Re: [R] 'persp' query
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.) -- David.
