spatialWeightMatrix

Create weight matrix for spatial data

spatialWeightMatrix(x, span = NULL)

Arguments

x

a matrix with rows corresponding to cells and columns corresponding to dimensions to calculate Euclidean distance

span

proportion of samples to include on either side, default is 13/(number of rows in `x`), corresponding roughly to points within a diamond shape distance away

Value

A weighted matrix

Examples

spat_x <- rnorm(50)
spat_y <- rnorm(50)
spat_coord <- cbind(spat_x, spat_y)
W <- spatialWeightMatrix(spat_coord)
#> span not specified, defaulting to 0.26
