comtradr 1.0.4
CRAN release: 2025-09-27
- patched ct_get_ref_table to also return reporterCodeIsoAlpha2 and partnerCodeIsoAlpha2, see: https://github.com/ropensci/comtradr/issues/94
- patched an error, where the wrong object was initialised for EB02 for querying services, see: https://github.com/ropensci/comtradr/issues/96
- thanks to luifrancgom and possakorn for pointing and fixing errors
comtradr 1.0.3
CRAN release: 2024-11-15
- this is a patch to fix a bug that was introduced when fixing the bug about tidy cols. Now tidy cols are returned again.
- testing for this error was introduced in the test environment to avoid this in the future.
comtradr 1.0.2
CRAN release: 2024-09-20
- this is a patch to fix two bugs in the package:
- a missing return in the call to tidy_cols did not allow users to set this argument to false, see https://github.com/ropensci/comtradr/issues/88 and commit 6f34592 (thanks @FATelarico)
- a missing parameter in the file size conversion function did not allow the bulk facility to download small files. This has been fixed.
comtradr 1.0.1
CRAN release: 2024-05-24
this is a patch to fix a CRAN policy violation, namely that the cache was written in the wrong directory due to using rappdirs.
If you have used comtradr prior to version 1.0.1 I recommend running
ct_migrate_cache()to copy files to the new cache and remove the old cache

ct_register_token()now properly bumps the hourly rate limit up to 10,000 (#21).In func
ct_search(), passing a character vector of long-form commodity descriptions to argcommod_codeswill now throw an error prior to making an API call, which would fail (#24).Update the country package data, to stay up to date with the reporter/partner country table that Comtrade is using. This is an update to the file
inst/extdata/country_table.rda. (#29).In func
ct_search(), improve error messaging when an input country is invalid. (#31).In func
ct_search(), fix bug in which running queries using theSITCrev2commodity type was returning raw HTML (as opposed to json data). (#27).In func

EB02within functionct_search(), passing"TOTAL"to argcommod_codesno longer returns zero results (#7). -
ct_commodity_lookup()no longer returns zero results when passing all caps input to argsearch_terms(#9).
comtradr 0.1.0
CRAN release: 2017-10-24
PKG API CHANGES

ct_commodities_tableandct_countries_table. - Added new functions
ct_update_databases,ct_use_pretty_cols,ct_commodity_db_type,ct_register_token,ct_get_reset_time,ct_get_remaining_hourly_queries. - Renamed functions:
commodity_lookupis nowct_commodity_lookup,country_lookupis nowct_country_lookup. - The commodity and country reference tables are now saved as cached package data, and accessed by
comtradrfunctions when necessary. This replaces the need for functionsct_commodities_tableandct_countries_table. - Reorder function arguments within function
ct_search. - Changed some function argument names to ensure
snake_caseis being used throughout the package. -
ct_searchnow returns a data frame, as opposed to a list.

-
Importschanges: removedplyr, addmagrittrandpurrr. - Expand and improve test coverage via testthat.
BUG FIXES
- The issues related to type-safety in function
commodity_lookuphave been fixed by importingpurrrand usingpurrr::mapin place ofsapply. This fixes issue #2 and issue #3.
