Find values at specified timepoints from curves specified as all corners of step functions.
timepoints(w, times)
A list with components
a matrix of estimates of the subdistributions with a row for
each component in w
and a column for each time
a matrix giving the corresponding variances.
a list containing the estimates, with points for all corners of the step function. (Usually created by cuminc.) Each component in the list contains the estimate for a different group. Each component has components giving times, function estimates, and variances (see cuminc)
vector of times where estimates are needed
