" h produces the estimated hazard component deltaH_j = H(t_j) - H(t_(j-1)), where t_j is the current failure time and t_(j-1) is the previous one. This is mainly a utility function used to calculate the estimated cumulative hazard H(t_j), yet you can estimate the hazard via a kernel smooth of the deltaH_j..."
