duration_compare {telemetR}

Compare the duration of Potential Blanking Periods

Description

Takes a dataframe of detection data which has been condensed by potential blanking periods generated by 'blanking_event()' and compares the duration of each event to a common sequence of increasing times. If the event is longer than the duration it is flagged as "survived". The proportion of events which "survive" for each potential blanking period at each time (t) is then calculated.

Usage

duration_compare(event_dur, var_groups = NULL, time_seq)

Arguments

event_dur

the detection dataframe which has been condensed into discrete events using each potential blanking period.

var_groups

a single string or vector of strings of the columns which should be used to group organisms. Common groupings are species and cohorts.

time_seq

a vector of times on the same scale as the ping rate. The largest value of the sequence should be greater that the longest duration produced using blanking event, and the smallest should be shorter than the smallest blanking period.

Value

A dataframe which contains the proportion of "survived" events created by each potential blanking period for each time (t).

Examples

# Compare the durations of blanked detection events
duration_compare(event_dur = blanked_detects,
                 var_groups = "fish_type",
                 time_seq = c(1:10))
