Plot the estimated coefficient function(s) from a fit
of Aalen's additive regression model.
USAGE:
plot.aareg(x, se=T, maxtime, ...)
REQUIRED ARGUMENTS:
x
the result of a call to the aareg function.
OPTIONAL ARGUMENTS:
se
if TRUE, standard error bands are included on the plot.
maxtime
upper limit for the x-axis.
...
other graphical parameters such as line type, color, or axis labels.
SIDE EFFECTS:
A plot is produced on the current graphical device.

EXAMPLES:
fit <- aareg(Surv(time, status) ~ age + sex + ph.ecog, data=lung,
na.action=na.omit)
plot(fit[1]) # plot of the intercept term versus time
plot(fit[3]) # the plot for the 'sex' coefficient
