Information on intervals in which times fall
get_intervals(x, times, ...)
# S3 method for default
get_intervals(x, times, left.open = TRUE, rightmost.closed = TRUE, ...)An object from which interval information can be obtained,
see int_info.
A vector of times for which corresponding interval information should be returned.
Further arguments passed to findInterval.
logical; if true all the intervals are open at left
and closed at right; in the formulas below, \(\le\) should be
swapped with \(<\) (and \(>\) with \(\ge\)), and
rightmost.closed means ‘leftmost is closed’. This may
be useful, e.g., in survival analysis computations.
logical; if true, the rightmost interval,
vec[N-1] .. vec[N] is treated as closed, see below.
A data.frame containing information on intervals in which
values of times fall.
