Im trying to censored in the right and it is not working. My code is the following:
km_fit <- survfit(Surv(mes, mes_2, estado, type = 'interval2') ~ 1,data = survival_clientes)
However, if I try with type = 'interval' it works.
I need interval2 because i have NAs for the right truncation, and this is really important to get the right interpretation.
