Dear Lorenzo, No, the code does not do what you are after. R-package transport is for point patterns and histograms in two and more dimensions. You have a distribution in one dimension. > 1) two distributions with the same bins (I identify each bin by the > central point in the bin). > > n_bin

Dear Dominic, Thanks a lot for the quick reply. Just a few questions to make sure I got it all right (I now understand that transport and spatstat in particular can do much more than I need right now). Essentially I am after the Wasserstein distance between univariate distributions (and it would b

Dear Lorenzo, The code you have attached (if you replace 00 by 50) generates two sets of 50 points each that are uniformly distributed on the unit square [0,1]^2 and then computes the Wasserstein-1 distance between them assuming that each point has mass 1/50. Do the following to get a plot of t
