> F_t=1-L_t Error in 1 - L_t : non-numeric argument to binary operator L_t is a list. You cannot subtract a list (at least in R). I'm not sure what you think F_t is supposed to be and you don't seem to use it. If you are attempting to calculate the Hazard function, it's just: str(L_t) # note the hazard component of that list. res$hazard [1] 0.03958 0.04121 0.04299 0.04492 0.04703 0.04935 0.05191 0.05476 [9] 0.05793 0.06149 0.06552 0.07011 0.07540 0.08155 0.08879 0.09744 [17] 0.10795 0.12102 0.13768 0.15966 0.19000 0.23457 0.30645 0.44186 [25] 1.00000 For some interpretations of your question, this may be what you are seeking.

I'm guessing you wanted the estimated Hazard. If I'm wrong, I wonder if you can rephrase the question so it makes more sense to a general statistical audience.
