Plot Method for icsurvfit Objects — plot.icsurvfit • IntCens

Plots the estimated survival function from an icsurvfit object. If model="NP", the nonparametric estimate is plotted. For model="PO" or "PH", the survival curve for a specific covariate value z can be overlaid. By default, it plots a step function.

Usage

# S3 method for class 'icsurvfit'
plot(
  object,
  z = NULL,
  xlab = "Time",
  ylab = "Survival rate",
  lty = 1,
  frame.plot = FALSE,
  add = FALSE,
  ylim = c(0, 1),
  ...
)

Arguments

object: An object of class "icsurvfit" returned by icsurvfit.
z: Numeric (vector of) covariate values for which to plot the survival curve. If NULL (default) and model is nonparametric, plots the baseline curve.
xlab, ylab: Axis labels.
lty: Line type. Default is 1.
frame.plot: Logical indicating whether to draw a box around the plot.
add: Logical indicating whether to add the curve to an existing plot. If FALSE (default), a new plot is created.
ylim: Numeric vector of length 2 specifying the \(y\)-axis range.
...: Additional graphical parameters passed to plot or lines.
