...o be 1:3 and (2) the logic that needs to be adhered to in order to reliably match up the sphere plot with the image plot.
library(misc3d)
##Set up array:
arr <- array(1:27, dim = rep(3,3))
## Plot image, with x, y, z positions all set (I thought) to 1:3
image3d(arr, x = 1:3, y = 1:3, z = 1:3, vlim = quantile(arr, c(0.01, 0.99)))
## Add spheres of the same data at the same positions
spheres3d(x=expand.grid(x = 1:3, y = 1:3, z = 1:3), radius = 0.1 *sqrt(arr))
## Ooops! So why don't they match up? Add axes:
axes3d()
## For some reason the image3d is generating negative values of z...
