View source: R/SegLocal-class.R

Create a new object of SegLocal-class from a matrix of coordinates and population data.

1	SegLocal(coords, data, env, proj4string = CRS(as.character(NA)))

`coords`	a numeric matrix or data frame with coordinates (each row is a point).
`data`	an object of class `matrix` containing the population data at each data point. The number of rows in ‘data’ should equal the number of points in ‘coords’, and the number of columns should be greater than one (i.e., at least two population groups are required).
`env`	an object of class `matrix` containing the local environment parameters. Must be the same dimensions as ‘data’.
`proj4string`	an optional projection string of class `CRS`.

An object of SegLocal-class.

pop <- matrix(runif(150), ncol = 3)
colnames(pop) <- LETTERS[1:3]

# constructs an object of class 'SegLocal'
v <- SegLocal(coords = xy, data = pop, env = pop)
