Buffer points in XY space

Description

Returns the original data table with buffered points removed.

Runs numerous iterations, as the random point selection can result in more/fewer output points.

1. Randomly select a single point

2. Remove points within 50km of that point

3. Randomly select of the remaining points

Usage

buffer_f(foo, buffer, reps)

Arguments

foo	a data.frame to select from with columns x, y
buffer	the minimum distance between output points
reps	the number of repetitions for the points selection
