Function for adding to an already existing graphical window
the predicted (excess) hazard or (net) survival based on a predMexhaz object.
Usage
## S3 method for class 'predMexhaz'
points(x,which=c("surv","hazard"),conf.int=TRUE, ...)
Arguments
x
an object of class predMexhaz, corresponding to
(excess) hazard and (net) survival predictions based on a survival
model fitted with the mexhaz function. Predictions can be
obtained for multiple times for one vector of covariates
("multitime") or for several vectors of covariates at one
time point ("multiobs"). The points() function only
applies to the "multitime" type of predictions.
which
the type of curve to be plotted. Selection can be made
between "surv" (default value) for the (net) survival curve
and "hazard" for the (excess) hazard.
conf.int
logical values allowing the user to decide whether to
plot the 95% confidence limits of the survival (or hazard), if
confidence limits are available in the predMexhaz object.
...
additional parameters that are directly passed to the points function.

Examples
data(simdatn1)
## Fit of a fixed-effect hazard model, with the baseline hazard
## described by a linear B-spline with two knots at 1 and 5 year and with
## effects of age (agecr), deprivation index (depindex) and sex (IsexH)
Mod_bs1_2 <- mexhaz(formula=Surv(time=timesurv,
event=vstat)~agecr+depindex+IsexH, data=simdatn1, base="exp.bs",
degree=1, knots=c(1,5), verbose=0)
## Prediction at several time points for one vector of covariates
Pred_Modbs1_2A <- predMexhaz(Mod_bs1_2, time.pts=seq(0.1,10,by=0.1),
data.val=data.frame(agecr=0,depindex=0.5,IsexH=1), conf.int="delta")
plot(Pred_Modbs1_2A,which="hazard",col="red")
points(Pred_Modbs1_2A,which="hazard",conf.int=FALSE)
