predict.smooth.sspline: Spherical Smoothing Spline Prediction

In sspline: Smoothing Splines on the Sphere

Description

Make prediction on the sphere using the information got from a smooth.sspline object.

Usage

  ## S3 method for class 'smooth.sspline'
predict(object, lon, lat, grid=FALSE, ...)

Arguments

object	a smooth.sspline object
lon	the longitudes on which the prediction is to be made
lat	the latitudes on which the prediction is to be made
grid	whether the prediction is on a grid
...	other parameters, not used

Details

It calls Fortran subroutine with the .Fortran interface.

Value

If grid = TRUE, return a matrix with dimension (length(lon), length(lat)); otherwise, return a vector of length = length(lon).

Note

The longitudes and latitudes are measured in degrees.
