[R] Computing Mean Lifetime from Hazard

Hello, If all I have access to is an empirically calculated hazard function, is it possible to compute an approximate value for the mean lifetime? I know that if the hazard function is essentially constant, the mean lifetime is 1/hazard rate.  But if I'm confident that the empirical hazard func
