int_info {pammtools} | R Documentation |
Given interval breaks points, returns data frame with information on
interval start time, interval end time, interval length and a factor
variable indicating the interval (left open intervals). If an object of class
ped
is provided, extracts unique interval information from object.

Currently ignored. |
min_time |
Only intervals that have lower borders larger than this value will be included in the resulting data frame. |
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 indicating the intervals.
