Hi, I am trying to specify four ticks (at 0,1,2,3 for the y axis) in a persp
plot but the defaults overrule my specification and I obtain seven of them.
Is it possible to gain full control over them in such a plot? Here is my
code:
matlines=matrix(c(1:7,3:9,3:9,2:8),nrow=7,ncol=4)
persp(x=seq(1,7,1),y=seq(0,3,1),z=matlines,theta=-30,phi=25,zlim=c(0,10),d=5,ticktype="detailed",xlab="x",
ylab="y",zlab="z")
I don't think there is any way to specify the locations with persp.
(You can use nticks=4 to reduce the number of ticks on all axes.)
persp3d in the rgl package gives you more control, but with less
flexibility about graphics devices.
