mem | R Documentation |
Computes the positive Moran's Eigenvector Maps of a distance matrix.
mem( distance.matrix = NULL, distance.threshold = 0, colnames.prefix = "mem" )
distance.matrix |
Distance matrix. Default: |
distance.threshold |
Numeric vector with distance thresholds defining different neighborhood extents within the distance matrix, Default: 0 |
colnames.prefix |
Character, name prefix for the output columns. Default: |
Takes the distance matrix x
, double-centers it with double_center_distance_matrix()
, applies eigen, and returns eigenvectors with positive normalized eigenvalues (a.k.a Moran's Eigenvector Maps, or MEMs). These MEMs are later used as spatial predictors by rf_spatial()
.
A data frame with positive Moran's Eigenvector Maps.
