sample_locations_uniform: Sample from a particular polygon shapefile

In spew: SPEW Framework for Generating Synthetic Ecosystems

Description

Sample from a particular polygon shapefile

Usage

sample_locations_uniform(place_id, n_house, shapefile, noise = 0.001,
  shapefile_id = NULL)

Arguments

place_id	numeric specifiying the ID of the region we are subsampling
n_house	numeric indicating the number of households
shapefile	sp class with all of the locations for each place id
noise	numeric indicating how must noise to add to sampled points This is only used if the number of points to sample exceeds 100,000, in which case the spsample function takes too long. Instead, we sample 100,000 points, sample n_house from these 100,000, and then add random noise.
shapefile_id	optionally include a shapefile id for subsetting shapefile

Value

SpatialPoints object with coordinates for the n households
