[R] scatterplot3d with categorical data

[Geoff Russell]

Dear users,

I'm trying to produce a 3d bar plot but the x and y dimensions have categorical
data -- so I only want 3 points on each axis. So I try:


require(scatterplot3d)

   mymat<-data.frame(
   x=c(1,1,1,2,2,2,3,3,3),
   y=c(1,2,3,1,2,3,1,2,3),
   z=c(1,2,3,4,5,6,7,8,9))
   scatterplot3d(mymat,
   type="h", lwd=5, pch=" ",
   xlab="xlabel", ylab="ylabel", zlab="zlabel",
   xlim=c(1,3), ylim=c(1,3),
   lab=c(3,3),
   x.ticklabs=c("Low","Medium","High"), y.ticklabs=c("Green","Blue","Black"),
   main="My Bar Plot")

But I still get x ticks at 1, 1.5, 2, 2.5, 3 on both x and y axes. I
thought lab
controlled this (according to the documentation).

What am I doing wrong, or is there some restriction on the way the
function works?

Cheers,
Geoff Russell
