plot.smooth.sspline: Plot a Smooth.sspline Object

In sspline: Smoothing Splines on the Sphere

Description

Plot a smoothing spherical spline using color to represent the function value.

Usage

  ## S3 method for class 'smooth.sspline'
plot(x, lon, lat, main="", xlab="Longitude",
     ylab="Latitude", key.title="Temp\n(deg)", ...)

Arguments

x	a smooth.sspline object
lon	the longitudes on which the function values will be calculated
lat	the latitudes on which the function values will be calculated
main	the main title of the plot
xlab	the x-axis label of the main plot
ylab	the y-axis label of the main plot
key.title	the title for the colored key
...	other plotting parameters, such as lwd, asp, and ...

Details

It calls predict.smooth.sspline and filled.contour.

Value

NULL

Note

The longitudes and latitudes are measured in degrees.
