I’m announcing version 2.0.0 of the {ecmwfr} R package providing native R access to the Data Store products. The package now uses the latest beta API, which is set to replace the current one mid September. You can update using:
install.packages("ecmwfr")
Please update your R code in time to guarantee continued functionality. Please read the release note (blog post) carefully as there are some breaking changes to the API and more importantly to the data formats.
Although this release addresses some issues, including collisions between login credentials, the package is limited by the current API issues highlighted elsewhere on the forum such as data formatting and no full index of API functionality.
For those on other frameworks (.NET etc), feel free to go through the package code. It might help you migrate to the new API.
