Features

• Map of population time series in Québec, used to calculate the index
• Visual presentation of the Living Planet Index and of raw data at the province, species group, and population scale
• Information panels and modals to describe the index, its calculation, and its interpretation

Datasets

All visualisations available in this dashboard are based on data from the following sources: Living Planet Database SurVol Benthos (soon) * BioTIME (soon)

Get started

This is a Shiny app built as an R package. The package can be installed using the R package devtools, like so:

devtools::install_github("ReseauBiodiversiteQuebec/tableaulpi")

To run the app locally within the tableaulpi directory, run the following:

library(tableaulpi)
run_app()

There may be some differences between this local version and the published version due to additional styling when the dashboard gets published onto the server.

How tableaulpi works

Structure & styling

This dashboard was built using the golem framework (more information on this here).

Styling is done commonly to all dashboards in the RBDQ project via :star: :star: :star: mapselector :star: :star: :star: .

Reactivity

taxa via radioGroup buttons on main page: filters the map of population coordinates

clicked_population selects a population ID from the map, and opens a modal to show the population time series and some summary information about the population.

target_taxa via radioGroup buttons on IPV plot module, in each tab. Filters the plot by taxonomic group selected by the user.

target_years via radioGroup buttons on IPV plot module, tab 'Tendances dans le temps'. Filters the plot by the range of years selected by the user.

Modules

Specific to this app

mod_lpi_time_series.R

A shiny module to generate the user interface and server functions used to produce a time series plotly of the Living Planet Index for the selected taxonomic group. This plotly is generated using the function make_indextrend(). This plot appears when the Afficher l'IPV button is clicked on the current version of the dashboard.

mod_trend_distribution.R

A shiny module to generate the user interface and server functions used to produce a barplot (plotly) showing the proportion of populations that are declining, stable (between -5% and 5% mean annual change), or growing over a user-selected time period between 1950-2018. This plotly is generated using the function make_trend_distribution(). This plot appears when the IPV par groupe button is clicked on the current version of the dashboard.

mod_trend_perpopulation.R

A shiny module to generate the user interface and server functions used to produce a scatter plotly showing each population's growth rate over the entire period covered by the dashboard (currently set to 1990-2018). This plotly is generated using the function make_trend_perpopulation().

mod_subset_plot_leafletproxy.R

A shiny module to filter the point map on the home screen of the dashboard according to the selected taxonomic group in the sidebar using leaflet proxy.

Credits

This dashboard is an ever-evolving collaborative effort with the entire Réseau Biodiversité Québec team, with special thanks to Andrew Macdonald for code review, contributions, and the development of :star: :star: :star: mapselector :star: :star: :star:, Vincent Bellavance for ideas and help with conception and design, data, troubleshooting, and development, and Guillaume Larocque for help with design, development, troubleshooting, and a superhuman reactivity to the ever-evolving beast that is this project.

Wishlist

These are things that would enhance the dashboard, but are not necessary: - [ ] Show the clicked population's position in the ridgeplot distribution? - [ ] Show some rating of the certainty of the index, based on # of populations, # data points, etc.
