My data belong to subtype of TCGA breast cancer. I have to do survival analysis for this data set. I know "survival" package but I don't know how can I involve genes profiles to survival analysis. Surly, for OS analysis, I can use "survfit" as a function for survival analysis and by "Time" and "OS status" I can get my target. but really, I don't know how to input my transcriptom profile as input in my survival analysis. In other words, I want to know how can I gene survival analysis through "survival" package or another nice package. due to this research, I found "RTCGA" as a bioconductor package but it's not possible to customize arguments of "survivalTCGA" for for survival analysis about subtype of breasat cancer. I deeply appreciate if you share your comment with me.
