predict.surface.se: Standard errors of predictions

Description

Evaluates the standard error of predictions on a surface.

Usage

predict.surface.se(object, grid.list=NA, extrap=FALSE, chull.mask,
nx=80, ny=80,...)

Value

A surface object with components A vector of standard errors for the predicted values.

Details

This function is generic and will call the appropriate function to calculate the standard errors for the object class. It operation is simple a grid is created based on the grid list or from the fit object. The prediction standard error are evaluated on the grid using predict.se. Finally the standard errors are reformed into a surface object suitable for plotting.
