Sample by polygon, according to a specified sampling density
sample.by.poly(p, n.pts.per.ac = 1, min.samples = 5, sampling.type = "hexagonal", iterations = 10, ...)
p |
a Polygon object, with coordinates from a projected CRS |
n.pts.per.ac |
requested sampling density in points per acre (results will be close) |
min.samples |
minimum requested samples / polygon |
sampling.type |
sampling type, see |
iterations |
number of tries that |

additional arguments to |
This function is typically used within the context of a loop or similar function that iterates over a list of Polygons associated with a SpatialPolygons object. See examples.
A SpatialPoints object.
This function expects that the Polygon object has coordinates associated with a projected CRS– e.g. units of meters.
