What is fluxnet-package?

fluxnet keeps swapping its own plumbing — first a Python downloader, now a DuckDB backend.

fluxnet gives R users access to FLUXNET eddy covariance data: listing sites, downloading, quality control and citation. Two releases in three months replaced the parts underneath the user-facing functions — 0.3.0 moved downloading off httr2 onto the fluxnet_shuttle Python library, and 0.6.0 added experimental DuckDB ingest so data can be queried with dplyr without being read into memory. The API around them has been churning in step, with site_ids='all' deprecated and max_gapfill renamed to threshold.

What is rnpn?

The USA phenology data client rebuilt its entire stack and stopped handing users -9999 as a number.

rnpn is the R client for the USA National Phenology Network, retrieving observation records, phenometrics and gridded model layers. Version 1.3.0 in March 2025 replaced nearly all of its infrastructure at once — sp and raster dropped, terra made optional, XML swapped for xml2, plyr for dplyr, httr and curl for httr2 — and changed what functions return, with tibbles in place of data.tables and empty tibbles in place of NULL on error. The two releases since have completed the missing-value handling and restored performance lost in the transition.

fluxnet-package vs rnpn: editorial side-by-side

F0.0

fluxnet keeps swapping its own plumbing — first a Python downloader, now a DuckDB backend.

◆ Current state

fluxnet gives R users access to FLUXNET eddy covariance data: listing sites, downloading, quality control and citation. Two releases in three months replaced the parts underneath the user-facing functions — 0.3.0 moved downloading off httr2 onto the fluxnet_shuttle Python library, and 0.6.0 added experimental DuckDB ingest so data can be queried with dplyr without being read into memory. The API around them has been churning in step, with site_ids='all' deprecated and max_gapfill renamed to threshold.

◆ Where it's heading

The direction is toward handling data volumes that do not fit the read-it-all-into-R model, and toward borrowing rather than reimplementing — a Python library for transfers, DuckDB for storage. That comes with dependency weight the package now has to manage itself, which is what flux_install_shuttle() and its virtualenv handling exist for. Renames and deprecations in nearly every release suggest the interface is being fixed as the backend settles rather than the other way around.

◆ Prediction

The DuckDB functions are marked experimental and cover connect, build and update only, so the next step is most likely stabilising them and routing the existing quality-control and extraction functions through the database rather than around it.

The USA phenology data client rebuilt its entire stack and stopped handing users -9999 as a number.

◆ Current state

rnpn is the R client for the USA National Phenology Network, retrieving observation records, phenometrics and gridded model layers. Version 1.3.0 in March 2025 replaced nearly all of its infrastructure at once — sp and raster dropped, terra made optional, XML swapped for xml2, plyr for dplyr, httr and curl for httr2 — and changed what functions return, with tibbles in place of data.tables and empty tibbles in place of NULL on error. The two releases since have completed the missing-value handling and restored performance lost in the transition.

◆ Where it's heading

The package is being brought onto the current R stack and made honest about missing data, and those are the same project. Converting the -9999 sentinel to NA started in 1.3.0 for download functions and was extended to all columns in 1.4.1; the string "emptyvalue" got the same treatment. Beyond the migration, the feature additions are modest and specific to the domain, such as custom start and end dates for defining a phenometrics season.

◆ Prediction

With the dependency migration finished and sentinel handling now applied across all columns, the next releases most likely return to domain features and to fixes surfaced by the server side, which has already prompted work through migrations and backend moves. The removed progress indicator is an acknowledged regression that may come back.
