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 |

print.levels |
name(s) to be plotted. Default plots all levels. |

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.
