R Documentation

Figure - Cumulative Survival by Interval

Description

A function that returns a plot for Cumulative Survival by Interval supporting multiple selected years.

Usage

Plot.surv.int.multiyears(plotdata, fit, nJP, yearvar, 
                         obscumvar = "Relative_Survival_Cum", 
                         predcumvar = "Predicted_Survival_Cum", 
                         interval = "Interval", year.select = NULL)

Arguments

`plotdata`	Either of the following data set would work. 1) the graph data returned by function download.data with downloadtype="graph" and all intervals needed for int.col. 2) the full data returned by function download.data with downloadtype="full".
`fit`	The joinpoint object containing the model output.
`nJP`	The number of joinpoints in the model.
`yearvar`	The variable name for year of diagnosis used in argument 'year' of the function joinpoint.
`obscumvar`	The variable name for observed relative cumulative survival. The default is "Relative_Survival_Cum" for relative survival data. For cause-specific data, it needs to be changed accordingly.
`predcumvar`	The variable name for predicted cumulative survival. The default is "Predicted_Survival_Cum".
`interval`	The variable name for year since diagnosis. The default is 'Interval'.
`year.select`	The year values selected for the plot. The default is NULL.

Value

An object of class ggplot containing the plot.
