Kaplan-Meier

Kaplan-Meier plots using ggplots2 (updated)

About 3 years ago I published some code on this blog to draw a Kaplan-Meier plot using ggplot2. Since then, ggplot2 has been updated (from 0.8.9 to 0.9.3.1) and has changed syntactically. Since that post, I have also become comfortable with Git and Github. I have updated the code, edited it for a small error, and published it in a Gist. This gist has two functions, ggkm (basic Kaplan-Meier plot) and ggkmTable (enhanced Kaplan-Meier plot with table showing numbers at risk at various times).
