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

Description

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

Usage

plot.smooth.sspline(x, lon, lat, main="", xlab="Longitude",
    ylab="Latitude", key.title="Temp(deg)", ...)
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 ...}

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

[object Object]
The longitudes and latitudes are measured in degrees.
