collapse(), compute(), collect()query_set that lists all APIs that will be pinged (collapse()), send the queries to required APIs (compute()), and return data as a tibble (collect()) (#183).galah_filter(), galah_select() and related functions now evaluated lazily; no API calls are made until compute() is called, meaning that earlier programming stages are faster and easier to debug.galah_filter()galah_filter() has been upgraded to use a hierarchical parsing architecture suggested by Advanced R.

tibble as input to search_taxa() (e.g., to resolve homonyms, #168)galah_select() while atlas = GBIF (which is not supported; #181)... in galah_filter() (#186)An experimental feature of version 1.5.1 is the ability to call functions from other packages (#161), as synonyms for galah_ functions. These are:
identify() ({graphics}) as a synonym for galah_identify()select() ({dplyr}) as a synonym for galah_select()group_by() ({dplyr}) as a synonym for galah_group_by()slice_head() ({dplyr}) as a synonym for the limit argument in atlas_counts()st_crop() ({sf}) as a synonym for galah_polygon()count() ({dplyr}) as a synonym for atlas_counts()These are implemented as S3 methods for objects of class data_request, which are created by galah_call(). Hence new function names only work when piped after galah_call().
The Global Biodiversity Information Facility (GBIF) is the umbrella organisation to which all other atlases supply data. Hence it is logical to be able to query GBIF and it’s “nodes” (i.e. the living atlases) via a common API. Supported functions are:
search_taxa and galah_identify for name matchingshow_all(fields) and show_all(assertions)show_all() calls that give ‘collections’ information are limited to 20 records by default, as GBIF datasets are often huge. search_all() is generally more reliableshow_values() for any GBIF fieldgalah_filter and galah_group_by (and therefore filter and group_by(), see above), but NOT galah_select.atlas_counts() (and therefore count(), see above)atlas_occurrences() & atlas_species(); both are implemented via the ‘downloads’ system, meaning that queries can be larger, but may be slowThe current implementation is experimental and back-end changes are expected in future. Users who require a more stable implementation should use the {rgbif} package.
galah_config() gains a print function, and now uses fuzzy matching for the atlas field to match to region, organisation or acronym (as defined by show_all(atlases)). An example use case is to match to organisations via acronyms, e.g. galah_config(atlas = "ALA").readr::read_csv in place of utils::read.csv for improved speedshow_all (and associated sub-functions) gain a limit argument, set to NULL (i.e. no limit) by defaultgalah no longer imports {data.table}, since the only function previously used from that package (rbindlist) is duplicated by dplyr::bind_rowsurl_paginate() to handle cases where pagination is needed, but total data length is unknown (e.g. show_all_lists(), #170).galah_select(group = "assertions") is always enacted properly by atlas_occurrences, and won’t lead to overly long urls (#137). When called without any other field names, recordID is added to avoid triggering the ‘default’ set of columns.atlas_species works again after some minor changes to the API; but requires a registered email to functiongalah_call(), filtered with galah_ functions, and downloaded with atlas_ functions. Previously, this functionality was only possible with queries to the ALA (#126)collect_media()atlas_media() has been improved to use 2 simplified functions to show & download media (#145, #151):
atlas_media() returns a tibble of available media filescollect_media() downloads the list of media from atlas_media() to a local machinetype = "thumbnails" in collect_media() (#140)galah_geolocate()galah_geolocate() now supports filtering queries using polygons and bounding boxes. Overall improvements and bug fixes to galah_geolocate() through new internal functions galah_polygon() and galah_bbox() (#125)show_all(), search_all() & show_values(), search_values()show_all() and search_all() are flexible look-up functions that can search for all information in {galah}, rather than by separate search_/show_all_ functions (e.g. search_fields(), search_atlases(), show_all_fields(), show_all_reasons(), etc) (#127, #132)show_values() & search_values() (#131)galah_apply_profile() function (#130)galah_ functions (#133)galah_geolocate() no longer depends on archived {wellknown} package (#141)galah_filter(species != "") or galah_filter(species == "") (#143)collect_doi() (#140)galah_select() no longer adds “basic” group of columns automatically (#128)galah_config() doesn’t display incorrect preserve = TRUE message (#136)galah_select() (#137)atlas_counts() and atlas_occurrences() no longer return different record numbers when a field is empty (#138)atlas_media() results no longer differ to results returned by galah_filter() & atlas_counts() (#151)ala_ functions are renamed to use the prefix atlas_. This change reflects their functionality with international atlases (i.e., atlas_occurrences, atlas_counts, atlas_species, atlas_media, atlas_taxonomy, atlas_citation) (#103)select_taxa is replaced by 3 functions: galah_identify, search_taxa and search_identifiers. galah_identify is used when building data queries, whereas search_taxa and search_identifiers are now exclusively used to search for taxonomic information. Syntax changes are intended to reflect their usage and expected output (#112, #122)select_ functions are renamed to use the prefix galah_. Specifically, galah_filter, galah_select and galah_geolocate replace select_filters, select_columns and select_locations. These syntax changes reflect a move towards consistency with dplyr naming and functionality (#101, #108)find_ functions that provide a listing of all possible values renamed to show_all_ (i.e., show_all_profiles, show_all_ranks, show_all_atlases, show_all_cached_files, show_all_fields, show_all_reasons). find_ functions that require and input and return specific results renamed to search_ (i.e., search_field_values, search_profile_attributes) (#112, #113)galah_group_bygalah_group_by(), which groups and summarises record counts based on categorical field values, similar to dplyr::group_by() (#90, #95)galah_down_togalah_down_to() + atlas_taxonomy(), which uses tidy evaluation like other galah_ functions (#101, #120)galah_call|>, %>%) by first using galah_call(), narrowing queries with galah_ functions and finishing queries with an atlas_ function (#60, #120).galah_filter (#91, #92)search_taxa returns correct IDs for search terms with parentheses (#96)search_taxa returns best-fit taxonomic result when ranks are specified in data.frame or tibble (#115)search_taxonomy() renamed to ala_taxonomy()ala_taxonomy no longer fails for nodes ranked as informal or unranked (#86)data.tree packagegalahgalah_config()ala_config() has been renamed to galah_config() to improve internal consistency (#68)search_taxonomy()search_taxonomy() provides a means to search for taxonomic names and check the results are ‘correct’ before proceeding to download data via ala_occurrences(), ala_species() or ala_counts() (e.g., not ambiguous or homonymous) (#64 #75)search_taxonomy() returns information of author and authority of taxonomic names (#79)search_taxonomy() consistently orders column names, including in correct taxonomic order by rank (#81)find_cached_files() lists all user cached files and stored metadata (#57)clear_cached_files() removes previously cached files and stored metadata (#71)ala_counts(), ala_occurrences(), ala_media() and ala_species() now have refresh_cache argument to remove previously cached files and replace with the current query (#71)ala_media() caches media metadata if galah_config(caching = TRUE)search_fields() allows the user to pass a qid as an argument (#59)galah_config(run_checks = FALSE). This helps users avoid slowing down data request download speeds when many requests are made in quick succession via galah_filter() or ala_occurrences() (#61, #80)ala_counts(), select_columns() and search_fields() now use match.arg to approximate strings through fuzzy matching (#66)select_columns(group = 'assertions') now sends qa = includeall to ALA web service API to return all assertion columns (#48)ala_occurrences() returns data DOI when ala_occurrences(mint_doi = TRUE) and re-downloads data when called multiple times (#56)ala_occurrences() no longer converts field names with all-CAPS to camelCase (#62)ala_config() allows users to specify an international Atlas to download data from (#21)ala_media() includes the file path to the downloaded media in the returned metadata (#22)ala_occurrences() contains the search_url used to download records; this takes the user to the website search page (#32)ala_species() provides a more helpful error if no species are found (#39)select_taxa() has an optional all_ranks argument to return intermediate rank information (#35)select_taxa() behaves as expected when character strings of 32 or 36 characters are provided (#23)ala_occurrences() uses the columns as expected (#30)galah_filter() negates assertion filters when required, fixing the issue of assertion values being ignored (#27)select_taxa() no longer throws an error when queries of more than one term have a differing number of columns in the return value (#41)ala_counts() returns data.frame with consistent column classes when a group_by parameter is called multiple times and ala_config(caching = TRUE) (#47)ala_ functions fail gracefully if a non-id character string is passed (#49)ala_media() now takes the same select_ arguments as other ala_ functions (#18)search_fields now has media as a type argument optionverbose == TRUE (#8)galah_location auto-detects the type of argument provided and so takes a single argument, query, in place of sf and wkt (#17)select_taxa auto-detects the type of argument provided and so takes a single argument, query, in place of term and term_type (#16)ala_counts uses the group_by field name as the returned data.frame column name (#6)ala_occurrences sends sourceId parameter to ALA (#5)search_fields provides a more helpful error for invalid types (#11)First version of galah, built on earlier functionality from the ALA4R package.
