Plots a surface and contours

Usage

surface.nnreg(obj, grid.list=NA, extrap=F, ...)

Arguments

obj A nnreg object
grid.list A list with as many components as variables describing the surface. All components should have a single value except the two that give the grid points for evaluation. If the matrix or data frame has column names, these must appear in the grid list.
extrap Extraplolation beyond the range of the data.
... Any ploting options.

Description

Two plots are made, a surface plot and a contour plot.

Examples

nnreg(ozone$x,ozone$y,1,3) -> fit # fitting a surface to ozone
surface(fit) # plots surface and contours of nnreg fit

nnreg(as.matrix(BD[,1:4]),BD$lnya,1,1) -> fit # fitting a DNA strand
# displacement amplification surface to various buffer compositions
surface(fit,grid.list=list(MgCl2='x',dNTP='y',KCl=35,KPO4=20)) # plots 
# surface on MgCl2-dNTP grid at specific KCL and KPO4 levels
