camtrapdp 0.6.0

• 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

• 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

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

• New contributors() returns a tibble with contributors (#140).
• New individuals() returns a data frame with unique individuals (#149).
• taxa() now removes duplicates (#130).

Filtering data

• filter_deployments() and deployments()<- now update the spatial, temporal and taxonomic scope in the metadata based on the returned data (#100, #132).
• filter_observations(), filter_media(), media()<- and observations()<- now update the taxonomic scope in the metadata based on the returned data (#89, #100, #130).

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

• 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

• 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).
