R help - Apr 2005 - persp plot

Is there a way to mark specific tick points on x, y and z axes? 
 
Also, I'm trying to overlay a persp plot using the command lines(..) but it
doesn't appear to work, does anyone know why?
 
I'm also trying to rotate the persp plot using rotation but this doesn't
work either? I get the error
 
parameter "rotation" couldn't be set in high-level plot() function
 
does anyone know why?
 
Thanks for any help.

See the examples of ?persp how to add elements to an existing persp() 
plot, in particular the function trans3d() given in the examples.

Because it does not exist. See ?persp.
