int_info: Create start/end times and interval information

In adibender/ldatools: Utility functions for life-time data analysis

Description

Given interval breaks points, returns data frame with information on interval start time, interval end time, interval length and a interval factor variable (left open intervals). If object of class ped is provided, extracts unique interval information from object.

Usage

int_info(x, ...)

## Default S3 method:
int_info(x, right_closed = TRUE, min_time = 0L, ...)

Arguments

x	A numeric vector of cut points in which the follow-up should be partitioned in or object of class ped.
...	Currently ignored.
right_closed	Logical. If TRUE (default), intervals are assumed right_closed closed and left open. If FALSE left closed and right_closed open.
min_time	Only intervals that have lower borders larger than this value will be included in the resulting data frame.

Value

A data frame containing the start and end times of the intervals specified by the x argument. Additionally the interval length, interval mid-point and a factor variable of the intervals themselves.

Examples

## create interval information from cut points
int_info(c(1, 2.3, 5))
