We are celebrating the 1st anniversary of the survminer’s release on CRAN! Due to that fact I have prepared the most (uber platinum) customized survival plot that I could imagine. I went too far because it took over 30 parameters to create a graph..

survminer, a package for drawing easily beautiful and ‘ready-to-publish’ survival curves with the ‘number at risk’ table and ‘censoring count plot’, has became very popular at the end of a previous year. It happend due to 3 great methodology posts about Cox Proportional Hazards model and Survival Analysis basics by Alboukadel Kassambara (kassambara) published on STDHA

If you are working in the survival analysis field, you might be interested in reading the post covering the newest features in survminer: survminer 0.2.4

Right now, after a year of the first CRAN release, survminer has been downloaded 11k times and has been used and cited in several research articles:

Due to the celebration of it’s 1st anniversary on CRAN, I have prepared a long survival graph of Kaplan-Meier estimates of survival curves, where each option is described below. I think I went too far to present the possible customization of the graph because this example takes over 30 parameters!
