plot.fitfrail: Plot method for 'fitfrail' objects

In frailtySurv: General Semiparametric Shared Frailty Model

Plot method for fitfrail objects

Description

Plot the cumulative baseline hazard estimates or the parameter trace from model estimation.

Usage

## S3 method for class 'fitfrail'
plot(x, type = c("cumhaz", "trace"), ...)

Arguments

x	a fitfrail object
type	string, the type of plot. Can be either "cumhaz" to plot the mean estimated cumulative hazard or "trace" to plot the paramater and log-likelihood trace.
...	extra arguments include: CI for type="cumhaz", numeric confidence interval between 0 and 1. If CI=0, no confidence interval is displayed. Otherwise, the bootstrapped confidence interval is calculated and displayed. end for type="cumhaz", numeric x-axis limit (plot up to time end) show.loglik for type="trace", logical whether to show the log-likelihood trace.

Value

The plot object.

Examples

## Not run: 
data(drs)
fit.drs <- fitfrail(Surv(time, status) ~ treated + cluster(subject_id), 
                    drs, frailty="gamma")

# Plot the parameter and log-likelihood trace
plot(fit.drs, type="trace") 

# This may take a while to run. 
# Use parameter B to specify the number of repetitions in the weighted bootstrap
plot(fit.drs, type="cumhaz", CI=0.95)

## End(Not run)
