Times relative to an event (typically dosing)
Description
Times relative to an event (typically dosing)
Usage
time_calc(time_event, time_obs, units = NULL)
Arguments
time_event |
A vector of times for events |
time_obs |
A vector of times for observations |
units |
Passed to |
Value
A data.frame with columns for:
- event_number_before
The index of
time_event
that is the last one beforetime_obs
orNA
if none are before.- event_number_after
The index of
time_event
that is the first one aftertime_obs
orNA
if none are after.- time_before
The minimum time that the current
time_obs
is before atime_event
, 0 if at least onetime_obs == time_event
.- time_after
The minimum time that the current
time_obs
is after atime_event
, 0 if at least onetime_obs == time_event
.- time_after_first
The time after the first event (may be negative or positive).
time_after
and time_before
are calculated if they are at the same time as
a dose, they equal zero, and otherwise, they are calculated relative to the
dose number in the event_number_*
columns.
