spatialWeightMatrix {scHOT} | R Documentation |
Create weight matrix for spatial data
spatialWeightMatrix(x, span = NULL)
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 |
A weighted matrix
spat_x <- rnorm(50) spat_y <- rnorm(50) spat_coord <- cbind(spat_x, spat_y) W <- spatialWeightMatrix(spat_coord)
