...am relatively new to R (took a class 2 yrs ago ...), and am hoping someone can point me in the right direction for a problem I'd like to solve in R : I would like to calculate the relative mortality of a particular impairment, relative to the standard population. I.e. I'm trying to find S_relative(t) in the eqn below : S_impar(t) = S_standard(t) * S_relative(t) where S_standard(t) is the mortality of the general population, and S_impar is the mortality of the the impaired group under consideration. Is doing something like this possible in R ? I have a dataset for an impaired group c...
