samplePoints: Take Point Observations from a spatial field.

In nmmarquez/PointPolygon: Evaluate Point and Polygon Data Simulatneously

Description

Takes binomial trials from a probability field created by simField randomly from points on the field.

Usage

samplePoints(field, N, M, replace = TRUE, times = NULL, ...)

Arguments

field	field object which simulated underlying data
N	int 1, Number of points to simulate
M	int, Number of trials for each point either 1 or N long
replace	logical, replace pixel probabilities in sampling?
times	vector of int, times to sample from
...	further argumnets for compatibility

Value

data.frame with observation number, number of trials, and the id of the pixel that the trail took place in.

Examples

set.seed(123)
unitSim <- simField(
    N = 300, 
    offset = c(0.1, 0.2), 
    max.edge = c(0.05,0.2),
    beta0 = -2,
    betaList = list(
        list(type="random", value=2),
        list(type="spatial", value=-.5),
        list(type="cluster", value=-2)
    ))

samplePoints(unitSim, N=20, M=100)
