Illustration of using the R relsurv package with the colon data

This page is a placeholder for R code for calculating the Pohar-Perme estimate of marginal relative survival using the relsurv package applied to the colon data widely used for Stata tutorials on my website. The R code was written by Enoch Yi-Tung Chen, who has written a tutorial comparing the various software implementations.

Code comparing the estimates with four Stata packages (strs, stns, stpp, and stns) is available here.
