In stc04003/reReg: Recurrent Event Regression

Plot the Baseline Cumulative Rate Function and the Baseline Cumulative Hazard Function

Description

Plot the baseline cumulative rate function and the baseline cumulative hazard function (if applicable) for an reReg object.

Usage

## S3 method for class 'reReg'
plot(
  x,
  baseline = c("both", "rate", "hazard"),
  smooth = FALSE,
  newdata = NULL,
  frailty = NULL,
  showName = FALSE,
  control = list(),
  ...
)

Arguments

x	an object of class reReg, returned by the reReg function.
baseline	a character string specifying which baseline function to plot. baseline = "both" plot both the baseline cumulative rate and the baseline cumulative hazard function (if applicable) in separate panels within the same display (default). baseline = "rate" plot the baseline cumulative rate function. baseline = "hazard" plot the baseline cumulative hazard function.
smooth	an optional logical value indicating whether to add a smooth curve obtained from a monotone increasing P-splines implemented in package scam.
newdata	an optional data frame contains variables to include in the calculation of the cumulative rate function. If omitted, the baseline rate function will be plotted.
frailty	an optional vector to specify the shared frailty for newdata. If newdata is given and frailty is not specified, the
showName	an optional logical value indicating whether to label the curves when newdata is specified.
control	a list of control parameters. See Details.
...	additional graphical parameters to be passed to methods.

Details

The argument control consists of options with argument defaults to a list with the following values:

xlab

customizable x-label, default value is "Time".

ylab

customizable y-label, default value is empty.

main

customizable title, default value are "Baseline cumulative rate and hazard function" when baseline = "both", "Baseline cumulative rate function" when baseline = "rate", and "Baseline cumulative hazard function" when baseline = "hazard".

Value

A ggplot object.

Examples

data(simDat)
fm <- Recur(t.start %to% t.stop, id, event, status) ~ x1 + x2

fit <- reReg(fm, data = simDat, B = 0)
plot(fit)
plot(fit, xlab = "Time (days)", smooth = TRUE)

## Predicted cumulative rate and hazard given covariates
newdata <- expand.grid(x1 = 0:1, x2 = mean(simDat$x2))
plot(fit, newdata = newdata, showName = TRUE)
