camtrapdp (development version)

camtrapdp 0.6.1

CRAN release: 2026-10-23

  • write_camtrapdp() continues to write files in the v1 specification of Data Package, as required by the Camtrap DP standard. This is in preparation of an upcoming version of the frictionless dependency, which uses the v2 specification as default. Users can thus safely install the latest version of frictionless and still write valid Camtrap DP datasets (#221).

camtrapdp 0.6.0

CRAN release: 2026-07-31

  • camtrapdp now relies on R >= 4.1.0 and uses base pipes (|> rather than %>%) (#209).
  • camtrapdp now relies on frictionless >= 1.3.0 (#217).

camtrapdp 0.5.0

CRAN release: 2026-01-14

  • read_camtrapdp() now upgrades datasets to Camtrap DP 1.0.2 (#183) and provides help for unsupported versions (#198).
  • write_camtrapdp() now removes properties with NA values from x$taxonomic and x$contributors which caused datapackage.json to be invalid (#186).
  • write_eml()’s derived paragraph is now formatted as DocBook rather than HTML (#188).

camtrapdp 0.4.0

CRAN release: 2025-06-11

Reading and writing data

  • read_camtrapdp() now updates (or creates) the spatial, temporal and taxonomic scope in the metadata based on the data (#130, #164).
  • read_camtrapdp() now upgrades datasets to Camtrap DP 1.0.1. The internal function convert() has been renamed to upgrade() (#113).
  • New write_camtrapdp() writes a Camera Trap Data Package to disk as a datapackage.json and CSV files (#137). This means you can now read, update and write Camtrap DP datasets.

Accessing data

Filtering data

Transforming data

  • write_dwc() now adds dwc:identificationVerificationStatus for observations classified by humans with 100% certainty (#158).
  • write_dwc() now allows to create occurrences from media-based observations (#172).
  • New write_eml() transforms Camtrap DP metadata to EML (#99). This function is used by GBIF to create metadata for a dataset page.
  • New merge_camtrapdp() allows to merge two datasets (#112). This can be useful to combine data from multiple studies.
  • New round_coordinates() allows to fuzzy/generalize location information by rounding deployment latitude and longitude. It also updates coordinateUncertainty in the deployments and coordinatePrecision and spatial scope in the metadata (#106).
  • New shift_time() allows to shift/correct date-times in data and metadata for specified deploymentIDs and duration (#108).
  • New update_taxon() allows to update taxonomic information in data and metadata (#159).

Miscellaneous

  • camtrapdp now relies on (and is tested for) R version 3.6.0 or higher (#138).
  • Internal function build_taxa() is renamed to taxonomic() (#130).

camtrapdp 0.3.1

CRAN release: 2024-07-05

  • Fix CRAN note (#102).

camtrapdp 0.3.0

  • New function print() prints a human-readable summary of the Camera Trap Data Package (#8).
  • Fix fieldsEnclosedBy issue in meta.xml, so GBIF occurrence processing correctly handles commas in fields (#95).
  • Fix CRAN note (#94).

camtrapdp 0.2.1

CRAN release: 2024-06-05

  • First release on CRAN. 🎉
  • write_dwc() no longer writes to "." by default, since this is not allowed by CRAN policies. The user needs to explicitly define a directory (#79).

camtrapdp 0.2.0

  • New function read_camtrapdp() reads data files from a Camtrap DP into memory (#9). It will make the data easier to use, by assigning taxonomic information (found in the metadata) to the observations and eventIDs (found in the observations) to the media (#37).
  • New accessor functions deployments(), media() and observations() return a data frame with the deployments, media and observations respectively (#29). These functions also have an assignment equivalent (#50).
  • New accessor functions locations(), events() and taxa() return a data frame with unique locations, events and taxa respectively (#22, #57, #17).
  • New functions filter_deployments(), filter_observations() and filter_media() allow to filter data. They work similarly to dplyr’s filter() (#23).
  • New function write_dwc() transforms a Camera Trap Data Package to a Darwin Core Archive (#55).
  • New function example_package() returns the latest Camtrap DP example dataset and caches the result (#24, #67).
  • New function version() allows to get the version of a camtrapdp object.
  • New internal function check_camtrapdp() validates a camtrapdp object (#34).
  • New internal function convert() converts camtrapdp objects to the latest version. This function is currently not used, as the only supported version is Camtrap DP 1.0 (#9).
  • dplyr’s pipe (%>%) is included in NAMESPACE, so you don’t have to load dplyr (or magrittr) to use it (#56). %>% and .data are imported at package level, so they can be used in functions without namespace (#37).
