In gcastella/predRCT: Predicting the Remaining Time to Achieve the Total Number of Required Number of Patients or Events in an Ongoing Clinical Trial

Description

Calculate proabilities of event for a set/subset of patients in a time interval, using a given survival function.

Usage

probAB(patients = TRUE, data, start, end, last.time, FUN)

Arguments

patients	Subset of indices for which to calculate the probabilities
data	Dataset with the times of inclussion, withdrawals, censoring indicator, time of follow-up, ...
start,	end Start or end of the interval of which to calculate the probabilities.
last.time	Number of days elapsed since the beginning of the trial.
FUN	survival function used for calculating the probabilities. Usually output from survFUN().

Value

A vector with the probabilities with the same length as nrow(data[patients, , drop = FALSE]).
