Description Usage Arguments Author(s) References

Calculates Nelson-Aalen or Kaplan-Meier curves for infectious disease transmission using right-censored and/or left truncated data on contact intervals in ordered pairs of individuals and infectious contacts from external sources with individuals.

`formula`	A formula of the form "response ~ terms". The response must be an object returned by `Surv`. The terms are converted into a factor with a level corresponding to each unique combination of covariate values.
`sus`	A string giving the name of the variable indicating the susceptible member of each pair.
`data`	A data frame containing the variables named in `formula`.
`subset`	An expression indicating which rows of `data` should be included in the model fit. Default is to keep all rows.
`na.action`	A missing-data filter applied to `data` after `subset`. Defaults to `options()$na.action`.
`inithaz`	A named hazard function (up to a constant of proportionality) #' to be used in the first iteration. The formal arguments in the function need to match variable names `data` that appear in `formula`.
`maxit`	The maximum number of EM algorithm iterations.
