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, ...)

## Arguments

x

An object from which interval information can be obtained, see int_info.

times

A vector of times for which corresponding interval information should be returned.

...

Further arguments passed to findInterval.

left.open

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.

rightmost.closed

logical; if true, the rightmost interval, vec[N-1] .. vec[N] is treated as closed, see below.

## Value

A data.frame containing information on intervals in which values of times fall.

findInterval int_info
