lines method for sirspline-object

Description

Plot SIR spline lines with R base graphics

Usage

## S3 method for class 'sirspline'
lines(x, conf.int = TRUE, print.levels = NA, select.spline, ...)

Arguments

x	an object returned by function sirspline
conf.int	logical; default TRUE draws also the 95 confidence intervals
print.levels	name(s) to be plotted. Default plots all levels.
select.spline	select which spline variable (a number or a name) is plotted.
...	arguments passed on to lines()

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.

Value

Always returns NULL invisibly. This function is called for its side effects.
