surviplot

An R package for drawing survival curves with the number-at-risk displayed underneath.

The primary function "surviplot" draws a survival curve with the number at risk displayed underneath. Optionally, the hazard ratio, CI, and logrank P value are displayed if there are exactly two strata.

You can see a couple of examples here: http://www.cbs.dtu.dk/~eklund/surviplot/

History: surviplot vs. survplot

I originally called this package "survplot" and made it available on my website around 2009. Soon after, I discovered the existence of a function called "survplot" in the rms package with somewhat similar functionality. I was heartbroken. Worse, there seemed to be people out there who were getting the two packages confused.

After seven years of anguish I finally arrived at a satisfactory new name for my package: surviplot. Ta-dah! Phew.

Version 1.0.0 of surviplot is essentially the same as version 0.0.7 of survplot, except for the "survplot" -> "surviplot" thing.

For former users of "survplot", you just need to replace

## old
library(survplot)
survplot(...)

with

## new
library(surviplot)
surviplot(...)

Installation

You can install the latest version from GitHub like this:

## install.packages("devtools")
devtools::install_github("aroneklund/surviplot")
