heplot3d / rgl : example causes R GUI to crash
...riables=c("Ca", "Mg"))
## this works OK
heplot3d(soils.mod, variables=c("Mg", "Ca", "Na"))
## this crashes R, but it draws most of the plot first
heplot3d(soils.mod, variables = c("Mg", "Ca", "Na"), hypotheses =
"ContourSlope")
## linear.hypothesis does work on this:
> print(linear.hypothesis(soils.mod, "ContourSlope"), SSP=FALSE)
