[R] Nearest neighbors of a of 3D points

[Eric Leroy]

Hi,

I have a text file that contains the 3D coordinates of points and I want 
to plot the histogram of the nearest neighbors distance. I can import 
the xyz coordinates in R and each value x, y, z is stored in a numerical 
array. I discovered the nndist.pp3 function from the spatstat package 
that seems to do what I want. My problem is to create a pp3 object from 
the xyz values that I have.

Do you know how to do that ?

Best regards,
