predictProb.survfit function

Extract predicted survival probabilities from a survfit object

Extracts predicted survival probabilities for survival models fitted by survfit, providing an interface as required by pmpec.

## S3 method for class 'survfit'
predictProb(object, response, x, times, train.data, ...)

Arguments

• object: a fitted model of class survfit.
• response: survival object (with Surv(time, status), where time is an n-vector of censored survival times and status an n-vector containing survival status, coded with 0 and 1.
• x: n*p matrix of covariates.
• times: vector of evaluation time points.
• train.data: not used.
• ...: additional arguments, currently not used.

Returns

Matrix with probabilities for each evaluation time point in times(columns) and each new observation (rows).
