plot.fitfrail function

Plot method for fitfrail objects

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

## 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.

Returns

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)
