Understand your OTN data • otndo

entiendo /ˌenˈtjendo/ [ˌẽn̪ˈt̪jẽn̪.̪o]
Spanish, 1st person indicative; “I understand”

otndo /ˌoʊˈtjendo/ [ˌoʊ̪ˈt̪jẽn̪.d̪o]
English, bad pun; “I understand (OTN data)”

The purpose of otndo is to provide a high-level summary of your acoustic telemetry transmitter matches from the Ocean Tracking Network, all while putting the “network” back in “tracking network” by noting the related projects and investigators.

Installation

You can install the most-up-to-date version from R-universe or GitHub.

R-universe:

install.packages(
  "otndo",
  repos = c(
    "https://mhpob.r-universe.dev",
    "https://cloud.r-project.org"
  )
)

GitHub:

# install.packages("remotes")
remotes::install_github("mhpob/otndo")

Tag push summary example

This is a basic example of how you might use otndo to summarize your transmitter data:

# Download some example data
td <- file.path(tempdir(), "otndo_test_files")
dir.create(td)

download.file(
  paste0(
    "https://members.oceantrack.org/data/repository/pbsm/",
    "detection-extracts/pbsm_matched_detections_2018.zip"
  ),
  destfile = file.path(td, "pbsm_matched_detections_2018.zip")
)
unzip(file.path(td, "pbsm_matched_detections_2018.zip"),
  exdir = td
)


# Make a tag push summary
library(otndo)

make_tag_push_summary(
  matched = file.path(td, "pbsm_matched_detections_2018.csv")
)

You will get a report in your working directory with a few goodies!

A summary of the number of matched individuals and detections by researcher and project:

The overall extent of the projects to which your tags have been matched:

When your fish were heard in each project:

The ever-ubiquitous “abacus plot”, showing when each tag was heard, colored by project:

An interactive map showing detections by receiver:

A general estimate of the number of transmitters that were active at a given date:

Receiver push summary example

This is a basic example of how you might use otndo to summarize your receiver data:

# Download some example data

## Deployment metadata
download.file("https://members.oceantrack.org/data/repository/pbsm/data-and-metadata/2018/pbsm-instrument-deployment-short-form-2018.xls",
  destfile = file.path(td, "pbsm-instrument-deployment-short-form-2018.xls"),
  mode = "wb"
)

## Qualified detections
download.file("https://members.oceantrack.org/data/repository/pbsm/detection-extracts/pbsm_qualified_detections_2018.zip",
  destfile = file.path(td, "pbsm_qualified_detections_2018.zip")

unzip(file.path(td, "pbsm_qualified_detections_2018.zip"),
  exdir = td

## Unqualified detections
