Access and download data on plant and animal populations from various databases through NatureCounts, a service managed by Birds Canada.
See tutorials, documentation and articles on the naturecounts package Website
Installation
You can install the main version of naturecounts
from our R-Universe
install.packages("naturecounts",
repos = c(birdscanada = 'https://birdscanada.r-universe.dev',
CRAN = 'https://cloud.r-project.org'))
Usage
Fetching counts
Use the nc_count()
function to return collections and the number of observations in each for which you have access (here returns all collections associated with username sample).
nc_count(username = "sample")
#> # A tibble: 2 × 4
#> collection akn_level access nrecords
#> <chr> <int> <chr> <int>
#> 1 SAMPLE1 0 full 991
#> 2 SAMPLE2 0 full 995
Use the show = "all"
argument to show counts for all collections available (public or otherwise).
Fetching data
Fetch all observations of bittern which are available to user sample into a local data frame.
First find the species id
search_species("American Bittern")
#> # A tibble: 1 × 5
#> species_id scientific_name english_name french_name taxon_group
#> <int> <chr> <chr> <chr> <chr>
#> 1 2490 Botaurus lentiginosus American Bittern Butor d'Amérique BIRDS
Use this id with nc_data_dl()
. The info
parameter is a short description of what the data is being downloaded for.
bittern <- nc_data_dl(species = 2490, username = "sample",
info = "readme_example")
#> Using filters: species (2490); fields_set (BMDE2.00-min)
#> Collecting available records...
#> collection nrecords
#> 1 SAMPLE1 1
#> Total records: 1
#>
#> Downloading records for each collection:
#> SAMPLE1
#> Records 1 to 1 / 1
Alternatively, save the downloaded data as a SQLite database (bittern
).
bittern <- nc_data_dl(species = 2490, sql_db = "bittern", username = "sample",
info = "readme_example")
#> Using filters: species (2490); fields_set (BMDE2.00-min)
#> Collecting available records...
#> collection nrecords
#> 1 SAMPLE1 1
#> Total records: 1
#>
#> Database 'bittern.nc' does not exist, creating it...
#>
#> Downloading records for each collection:
#> SAMPLE1
#> Records 1 to 1 / 1
Authorizations
To access private/semi-public projects/collections you must sign up for a free NatureCounts account and register for the projects you’d like to access. Once registered, you can use the username
argument (you will be prompted for a password) for both nc_count()
and nc_data_dl()
, which will then return a different set of records.
nc_count(username = "my_user_name")
bittern <- nc_data_dl(species = 2490, username = "my_user_name", info = "readme_example")
More advanced options
nc_count()
and nc_data_dl()
have a variety of arguments that allow you to filter the counts/data prior to downloading. These options include collections
, species
, years
, doy
(day-of-year), region
, and site_type
(users can specify up to 3 of these). For nc_data_dl()
you have the additional arguments fields_set
and fields
with which you can customize which fields/columns to include in your download.
See the function examples (nc_count()
, nc_data_dl()
) the following articles for more information on these filters:
- Collections
- Species Codes
- Regional Codes
- IBAs and BCRs (regions)
- Using spatial data to filter observations
We also have an article on post-filtering your data
Metadata
NatureCounts includes a great deal of metadata which can be accessed through the functions with the meta_
prefix. See the Meta Documentation for specifics.
