Dear Colleagues, Does anyone know how to specify nested models for kriging (krige.conv) in the function cov.spatial ? I have understood that I can specify a matrix of parameters using 'cov.pars = '. However, then I should specify the kind of model for each row of the matrix. The parameter 'cov.model' only accepts one keyword. Is this a bug?
