surface.addreg {funfits} | R Documentation |
Two plots are made, a surface plot and a contour plot.
surface.addreg(obj, grid.list=NA, extrap=F, graphics.reset=T, ...)
obj |
A addreg 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. |
graphics.reset |
Reset to original graphics parameters after function plotting. |
... |
Any plotting arguments. |
