Plot survival curves
Description
Plot survival curves
Usage
survParamPlot(formula, shape, points = NULL, n = 100, scale = 1, limits = NULL)
Arguments
formula |
This is the "formula" parameter of the Weibull-based survival curve that can be used to define the scale of the distribution. |
shape |
The parameter that defines the shape of the distribution. |
points |
An optional list of two-element vectors specifying the desired time and probability pairs that define the desired survival curve. If no list is specified then the plot will not include any points. |
n |
The number of points along the curve that will be used to define the line. Defaults to 100. |
scale |
An optional scale parameter that defaults to 1. If the value is 1, the scale of the distribution is determined entirely by the argument "f". |
limits |
A vector of length 2 that specifies x-axis limits for the plot. The default is NULL, in which case no limits are imposed. |
Value
A ggplot of the survival curve defined by the specified parameters. If the argument points is specified, the plot will include them
Examples
points <- list(c(60, 0.90), c(100, .75), c(200, .25), c(250, .10))
r <- survGetParams(points)
survParamPlot(r[1], r[2])
survParamPlot(r[1], r[2], points = points)
survParamPlot(r[1], r[2], points = points, limits = c(0, 100))
