Arguments

x

an object returned by function sirspline

Details

In lines.sirspline most of graphical parameters is user adjustable. Desired spline variable can be selected with select.spline and only one can be plotted at a time. The spline variable can include several levels, e.g. gender (these are the levels of print from sirspline). All levels are printed by default, but a specific level can be selected using argument print.levels. Printing the levels separately enables e.g. to give different colours for each level.
