spatialWeightMatrix: spatialWeightMatrix

In scHOT: single-cell higher order testing

Description

Create weight matrix for spatial data

Usage

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)
