Pick Neighbor

pick_neighbor(
  ranks,
  probs,
  distances = NA,
  sample_method = "rank",
  exponent = 1,
  group_size = 2
)

`ranks`	ranks for each point. If based upon a weighted distance, then may not directly correspond to the 'distances'.
`probs`	vector of probabilities. For `probs = c(p_1, p_2, p_3, p_4)`, the probability of the first NN being selected in `p_1`, the probability of the second is `p_2`, and so on
`distances`	distance to each point. Only used if sample_method = "exp" #' @param sample_method if equal to "rank", the probability of a point of rank x being chosen as a guest is probs[x]. If equal to "exp", the probability of a point of rank x being chosen as a guest is probs[x] exp(-exponent * distances[ranks]))*
`exponent`	a numeric. If sample_method = "exp", then this is the value of exponent in exp(-exponent distances[ranks])*
`group_size`	a numeric. How large will the groups be. Pick 'group_size -1' neighbors
