Fast, Simple API Tools for Retrieving Data from 'DeltaBreed' R package deltabreedquery version 1.0.3 Simplified data retrieval from the 'DeltaBreed' breeding data management platform (<https://sandbox.breedinginsight.net/>) via the 'BrAPI' open-source breeding data API (<https://brapi.org/specification>). Each of the four main data types stored in 'DeltaBreed' (germplasm, trait variables, experiments/environments, and observations) are handled by a get_datatype() function that constructs and executes the request, handles paginated responses, and parses the retrieved data. Responses are reformatted into a consistent, R-friendly data frame format that resembles how the data appears on the 'DeltaBreed' web interface as closely as possible.
