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

Description

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

Usage

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

Value

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

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.
