R Question

How to get correct ticklabs in a 3d-scatterplot in R?

Please see this example. Look at

y
axis. The data there has only two levels:
1
and
2
. But in the plot 6 tickmarks drawn on that axis. How could I fix that. The
x
axis has the same problem.

The data

extra group ID
1 0.7 1 1
2 -1.6 1 2
3 -0.2 1 3
4 -1.2 1 4
5 -0.1 1 5
6 3.4 1 6
7 3.7 1 7
8 0.8 1 8
9 0.0 1 9
10 2.0 1 10
11 1.9 2 1
12 0.8 2 2
13 1.1 2 3
14 0.1 2 4
15 -0.1 2 5
16 4.4 2 6
17 5.5 2 7
18 1.6 2 8
19 4.6 2 9
20 3.4 2 10


The script

require('mise')
require('scatterplot3d')
mise() # clear the workspace

# example data
print(sleep)

# plot it
scatterplot3d(x=sleep$ID,
x.ticklabs=levels(sleep$ID),
y=sleep$group,
y.ticklabs=levels(sleep$group),
z=sleep$extra)


The result

Answer

How about this:

scatterplot3d(x=sleep$ID, y=sleep$extra, z=sleep$group, lab.z = c(1, 2))
