global_morans | R Documentation |
Computes the Global Moran's I statistic and expectation. Can produce spatial weights from an adjacency or sf data frame, in which case the spatial_mat is a contiguity matrix. Users can also provide a spatial_mat argument directly.
global_morans(shp, adj, wts, spatial_mat, epsg = 3857)
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. Optional if shp or adj provided. |
epsg |
numeric EPSG code to planarize to. Default is 3857. |
list
library(dplyr)
data('checkerboard')
checkerboard <- checkerboard %>% mutate(m = as.numeric((id + i) %% 2 == 0))
global_morans(shp = checkerboard, wts = checkerboard$m)
