Subject: Nearest neighbors of a of 3D points
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,
--
