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 ?
