check_exposure(x, start_x, rl_data)

Arguments

x: input data: vector or data frame with event times in seconds since tagon.
start_x: name (no quotes needed) of variable in x that gives event times. Not needed if x is a vector or has only one column.
rl_data: dataset with RL data (output of extract_rls)

Value

A data.frame with the data and additional columns exposure_EventID (the ID number of the exposure event(s) during which this timestamp falls) and event_type (the type(s) of exposure events that were going on at this timestamp)
