A ggplot2 version of a Kaplan-Meier Plot
Usage
qkmplot(x, conf_int = FALSE, ...)
qkmplot_bulid_data_frame(x)
# S3 method for class 'survfit'
qkmplot_bulid_data_frame(x)
qrmst(x, tau = Inf)
# S3 method for class 'survfit'
qrmst(x, tau = Inf)
# S3 method for class 'qkmplot_data'
qrmst(x, tau = Inf)Details
Functions to build, explicitly or implicitly, data.frames and then creating a ggplot2 KM plot.
More details and examples for graphics within qwraps2 are in the vignette(“qwraps2-graphics”, package = “qwraps2”)
