[R] 3D Plot of Convex hull

[wwreith]

I have a data set in which I am trying to plot a convex hull in 3 dim. Below
is a subset of the points I would use. Columns 2,3,4 are my x,y,z
coordinates. I found some ways to plot 2D convext hulls or find a convex
hull for higher dimensions, but not how to plot the data. 

I have have attached an example of what I am shooting for in my plot. 

Thanks for the help!
