moranPoints:

In JusteRaimbault/r-spatialmorphology: What the package does (short line)

Usage

moranPoints(points, varcol, weights = spatialWeightsPoints(points))

Arguments

points
varcol
weights

Examples

##---- Should be DIRECTLY executable !! ----
##-- ==>  Define data, use random,
##--	or do  help(data=index)  for the standard data sets.

## The function is currently defined as
function (points, varcol, weights = spatialWeightsPoints(points)) 
{
    v = points[[varcol]]
    v = v - mean(v)
    num = sum(weights * (Diagonal(v) %*% Diagonal(v)))
    denom = sum(v^2)
    normalization = nrow(points)/sum(weights)
    return(normalization * num/denom)
  }
