Generate weight scheme that would be used in an additional aws step

Utility function to create a weighting scheme for an additional aws step. Inteded to be used for illustrations only.

awsweights(awsobj, spmin = 0.25, inx = NULL)

Arguments

awsobj	object obtained by a call to function aws
spmin	Size of the plateau in the adaptation kernel.
inx	either a matrix of dimension length(awsobj@dy) x number of points containing the integer coordinates of points of interest or NULL. In the latter case the weight scheme for all points is generated.

Value

an array of either dimension awsobj@dy x number of points or awsobj@dy x awsobj@dy
