phregR(formula, data, offset = NULL, weights = NULL, ...)
formula with 'Surv' outcome (see coxph
)
data frame

Robust variance is default variance with the summary.
influence functions (iid) will follow numerical order of given cluster variable so ordering after $id will give iid in order of data-set.
