local_gearys(shp, adj, wts, spatial_mat, epsg = 3857)

Arguments

shp: sf data frame. Optional if adj or spatial_mat provided.
adj: zero indexed adjacency list. Optional if shp or spatial_mat provided.
wts: Required. Numeric vector with weights to use for Moran's I.
spatial_mat: matrix of spatial weights. Not required if shp or adj provided.
epsg: numeric EPSG code to planarize to. Default is 3857.

Value

numeric vector

Examples

library(dplyr)
data('checkerboard')
checkerboard <- checkerboard %>% mutate(m = as.numeric((id + i) %% 2 == 0))
local_gearys(shp = checkerboard, wts = checkerboard$m)
