Hi everybody! I am trying to do survival analysis with TCGA-PRAD data. I learned how to do overall survival, KM plots and cox regression following this tutorial: https://bioconnector.github.io/workshops/r-survival.html , in which you learn how to use R packages "survival", "survminer" and TCGA data using the package "RTCGA".
My aim now is to do disease-free survival, but looking at the clinical data that i can download with RTCGA, I can't understand which columns I have to use, I can't see a clear indication of dfs. Also, checking here on biostars it seems that there are no other questions related specifically to it.
Can someone please help me to find a way to do this? Some example code will be really appreciated! Thank you a lot!!
