apc.plot {Epi} | R Documentation |
This function plots the estimates created by apc.fit
in a single
graph. It just calls apc.frame
after computing some sensible
values of the parameters, and subsequently plots the estimates using
apc.lines
.
apc.plot(obj, r.txt = "Rate", ...)
obj |
An object of class apc . |
r.txt |
The text to put on the vertical rate axis. |
... |
Additional arguments passed on to apc.lines . |
A numerical vector of length two, with names
c("cp.offset","RR.fac")
. The first is the offset for the cohort
period-axis, the second the multiplication factor for the rate-ratio
scale. Therefore, if you want to plot at (x,y)
in the right panel,
use (x-res["cp.offset"],y/res["RR.fac"])=(x-res[1],y/res[2])
.
This vector should be supplied for the parameter frame.par
to
apc.lines
if more sets of estimates is plotted in the
same graph.
