Resamples a set of points with x and y coordinates by increasing the distance step by step until a given sample size is obtained.
thinning_til_n( xy, n = 30, distance.step = NULL )
xy |
A data frame with columns named "x" and "y" representing geographic coordinates. Default: |
n |
Integer, number of samples to obtain. Must be lower than |
distance.step |
Numeric, distance step used during the thinning iterations. If |
A data frame with the same columns as xy with a row number close to n.
