[R] Adding plane in a 3D scatterplot

[Megh Dal]

I got following error :
> library(mnormt)
> library(scatterplot3d)
> dat = cbind(rmnorm(3, rep(0,2), diag(2)), 1:3)
> s3d <- scatterplot3d(dat, lab.z=2, scale.y=0.7, angle=20)
> s3d$plane3d(2,0,0, "solid", col="grey")
Error in object$coefficients : $ operator is invalid for atomic vectors
