空间相关性 (Spatial correlation)

  • ade4 - This package has function gearymoran that calculates Moran’s I and Geary’s c. Does not plot correlograms.
  • ape - Moran’s I test (function Moran.I) for spatial and phylogenetic autocorrelation (based on normal approximation, not on randomizations = fast). Does not plot correlograms.
  • geosphere - a bunch of spherical trigonometry functions for geographic applications.
  • mpmcorrelogram - I include it as a curiosity. It calculates Multivariate Mantel Correlograms.
  • ncf - Provides functions correlog and spline.correlog. Plots correlograms. Does randomization tests.
  • pgirmess - Has function correlog that calculates the correlogram. It uses normal approximation to test significance.
  • raster - Simple function Moran. Works on rasters. You need to specify a simple neighborhood matrix. Does not plot correlograms.
  • spatial - If I understand it correctly, this package first needs you to fit a trend surface (by kriging) and you can then calculate correlogram of this fitted surface. I haven’t gone deeper into it.

  • spdep - sp.correlogram, moran, moran.plot, moran.test, moran.mc. This is the most comprehensive package, and also the most difficult to work with. Does everything, has steep learning curve.
