Code Hub

NEON's data are often complex; working with data can be greatly simplified using software or code. We provide some code to get you started, like with our `neonUtilities` package for R, and also post links to code contributed by members of the community. The NEON-related code resources listed below are designed to make working with all NEON data easier, to perform common algorithms on select data products, and to share the code used to generate select  data products.

Most code resources that were created by and are managed by NEON can be found in the NEONScience GitHub organization. The code is free and open access to download and utilize. The code found in the NEONScience GitHub organization is published and maintained by NEON project scientists. 

Other code resources listed below are created by data users interested in sharing their code. If you have requests for coding resources, challenges with NEON data or ideas for creating NEON data-related code, we encourage you to learn more about how we categorize NEON-related code resources, and how you can submit your own code resources.

Code resources are provided at three tiers, differing in level of review by NEON:

Tier 1: Community Contributed Code	Community contributed code is reviewed to determine that it is publicly available, generally comprehensible, and involves NEON data. Code functionality is not evaluated.
Tier 2: NEON Certified Code	Certified code goes through a code review, to ensure it performs as described and without error.
Tier 3: NEON Production Code	Production code is used in NEON data processing pipelines, to generate NEON data products. It is the end product of a very long and careful development process.

Search the table below to find code that might be useful for your project.

Title	Description	Tier	Language
NEONiso This R package provides functions for downloading and calibrating atmospheric isotope data bundled into the eddy covariance data products. Tier 1: Community contributed code R language More Details This R package provides functions for downloading and calibrating atmospheric isotope data bundled into the eddy covariance data products. The carbon isotope calibration methods are described in Fiorella et al. (2021; JGR-Biogeosciences) and are available in the CRAN version of the package, while water isotope calibration methods remain in development on Github.

neonMicrobe This R package provides functions for working with NEON soil microbe data. Tier 1: Community contributed code R language More Details neonMicrobe is a suite of functions for downloading, pre-processing, and assembling heterogeneous data around the NEON soil microbe marker gene sequence data. To do so, neonMicrobe downloads NEON data products from the NEON Data API and processes sequences using the DADA2 workflow. Qin et al 2021 describes the functionality of this package in detail: https://esajournals.onlinelibrary.wiley.com/doi/full/10.1002/ecs2.3842 More Info Data products: DP1.10086.001 \| Soil physical and chemical properties, periodic, DP1.10108.001 \| Soil microbe marker gene sequences Contributor name: Clara Qin License: GNU General Public v3.0 Related collection system: TOS (Terrestrial Observation System)
neonNtrans This R package is for calculating soil extractable inorganic nitrogen (N) concentrations and net N transformation rates (mineralization and nitrification) from soil potassium chloride extracts. Tier 2: NEON certified code R language More Details More Info Data products: DP1.10080.001 \| Soil inorganic nitrogen pools and transformations Contributor name: Samantha Weintraub License: GNU Affero General Public v3.0 Related collection system: TOS (Terrestrial Observation System)
neonOS Perform common transformations on NEON observational data, including table joining and duplicate detection. Tier 2: NEON certified code R language More Details This R package provides functions for standardized duplicate checking and table-joining for NEON observational data products. It uses published metadata from the variables files and Quick Start Guides to determine the correct handling for each data product. neonOS is available via CRAN.

neonPlantEcology Reformat and process plant presence and percent cover data Tier 1: Community contributed code R language More Details This package contains scripts for processing plant species cover and occurrence data from NEON into more usable formats. The main functions are 'vegify', which creates vegan-friendly species occurrence and abundance matrices, and 'get_diversity_info', which creates summary statistics by plot (or subplot) on the diversity, cover, relative cover, and number of species of natives, non-natives, and members of the family or species of your choosing.

neonSoilFlux Provides soil carbon flux estimates and associated uncertainty as well as key environmental measurements that are used to compute soil fluxes. Tier 1: Community contributed code R language More Details Acquires and synthesizes soil carbon fluxes at sites located in the National Ecological Observatory Network (NEON). Provides flux estimates and associated uncertainty as well as key environmental measurements (soil water, temperature, CO2 concentration) that are used to compute soil fluxes.

neonstore This package provides a high-level interface for downloading and storing NEON data products. Tier 1: Community contributed code R language More Details Provides functions for downloading and storing NEON data files. By using persistent storage, this package avoids repeated downloading of the same data, but enables retention of older versions of data that have since been updated. This storage system facilitates reproducibility. Also includes an option to construct a local duckdb database to work with tables that are too large to store in memory.
