r - survival package, right censored data -


i account right censored data in analysis of dataset. using survival package - given cancer treatment tactics , when patient last checked in clients clinic.

is there suggested method or manipulation standard survival package account right-censored data?

our rows unique individual patients...

here our columns filled out:

  • list item
  • our treatment type (constant)
  • days since original diagnosis
  • 'censored' number of patients last heard on day. hence, uncertain if still alive or dead seen stopped attending clinic. should removed probability estimate @ points in future.
  • # of patients died on day (from original diagnosis)

so recommend manipulation of standard survival package? or using package? have seen survsnp, survpresmooth , survbivar may perhaps help. want avoid recalculations of individual columns/fields , creating new objects of r algorithm seeing small part of large dataset.
