add_org: Add Organism Data to a Detection Dataframe

Description

This function takes a prefiltered detection dataframe from `prefilter()` and joins it to organism data formatted using the `format_org()` function. Detections are then filtered further based on the date and time of tag release and expected battery life. Detections occurring before release of the tag or after 2x the expected battery life are removed.

Usage

add_org(prefilter_file, org, time_before_detection, time_unit)

Value

A filtered dataframe converting the raw detection data into rows of detections

Arguments

prefilter_file

a prefiltered detection dataframe from `prefilter()`

org

a dataframe of organism data retrieved from `get_org_data()` or `format_org()`

time_before_detection

How long before detection could an organism be released and still detected? Generally 2x the expected tag life.

time_unit

The unit of time used for time_before_detection (seconds, minutes, hours, days, weeks, months)

Examples

# Format the organism data
formatted_fish <- format_org(data = fish,
                             var_Id = "TagCode",
                             var_release = "Release_Date",
                             var_tag_life = "TagLife",
                             var_ping_rate = "PRI",
                             local_time_zone = "America/Los_Angeles",
                             time_format = "%Y-%m-%d %H:%M:%S")

# Add organism data to the prefiltered detection data
add_org(prefilter_file = dat_filt1,
        org = formatted_fish,
        time_before_detection = 120,
        time_unit = "days")
