Time intervals

Source: R/hesim_data.R

Create a table of time intervals given a vector or data frame of unique times. This would typically be passed to id_attributes.

time_intervals(times)

Arguments

times

Either a vector of starting times for each interval or a data.frame with at least one column named time_start.

Value

An object of class time_intervals that inherits from data.table in the same format as time_intervals as described in id_attributes.
