[R] Minimum Binding Box in 3D

[Lorenzo Isella]

Dear All,
I would like to know if anybody is aware of an R implementation of a
minimal bounding box ( http://bit.ly/2cKaSgT ) algorithm in R for
points in 3 dimensions.
It looks like there is no shortage of implementations in 2 dimensions,
e.g.

http://bit.ly/2cKaSh0
http://bit.ly/2cKboLS

but I cannot find any implementation for the 3D case.
Many thanks

Lorenzo
