plot.smoothSurvReg: Plot Objects of Class 'smoothSurvReg'

In smoothSurv: Survival Regression with Smoothed Error Distribution

Plot Objects of Class 'smoothSurvReg'

Description

Plot the fitted error distribution.

Usage

## S3 method for class 'smoothSurvReg'
plot(x, plot = TRUE, resid = TRUE, knots = TRUE,
   compare = TRUE, components = FALSE, standard = TRUE,
   by, toler.c = 1e-5,
   xlim, ylim,
   xlab = expression(epsilon), ylab = expression(paste("f(",epsilon,")", sep = "")),
   type = "l", lty = 1, main, sub, bty = "n", ...)

Arguments

x	Object of class smoothSurvReg.
plot	If TRUE the plot is directly produced, otherwise only a data.frame with information used for later plotting is returned.
resid	If resid & plot residuals are added to the plot in the following way. Residuals based on exact observations are plotted by pch = 3 (+), residuals based on right censored observations using pch = 4 (x), residuals based on left censored observations using pch = 2 (traingle) and midpoints of residuals based on interval censored observations using pch = 5 (diamond).
knots	If knots & plot bullets indicating (transformed) knots corresponding to 'c' G-spline coefficients higher than toler.c are added to the x-axis of the plot.
compare	If compare & !components & standard & plot plots of the three parametric distributions (st. normal, st. logistic and st. minimum extreme value) are added to the plot for comparison.
components	If components & standard & plot dashed lines with weighted G-spline components are added to the plot.
standard	If standard data for plotting the fitted error distribution are created, otherwise data for plotting the distribution of \alpha + \sigma\varepsilon are created. In the case that \log(\sigma) depends on covariates and standard is FALSE, all covariates equal to zero are used to compute \log(\sigma).
by	Step for a ploting grid. If NULL it is automatically computed.
toler.c	Tolerance to indicate zero 'c' G-spline coefficients used if knots == TRUE.
xlim, ylim	Arguments passed to the plot function.
xlab, ylab	Arguments passed to the plot function.
type, lty	Arguments passed to the plot function.
main, sub	Arguments passed to the plot function.
bty	Argument passed to the plot function.
...	Arguments passed to the plot function.

Value

A dataframe with columns named x and y where x gives the grid and y the values of the density at that grid.
