Models for Estimating Aquatic Photosynthesis and Respiration
Alison P. Appling, Robert O. Hall, Jr., Maite Arroita, and Charles B. Yackulic
The streamMetabolizer R package uses inverse modeling to estimate aquatic photosynthesis and respiration (collectively, metabolism) from time series data on dissolved oxygen, water temperature, depth, and light. The package assists with data preparation, handles data gaps during modeling, and provides tabular and graphical reports of model outputs. Several time-honored methods are implemented along with many promising new variants that produce more accurate and precise metabolism estimates.

Questions and bug reports
Please report bugs and ask questions on the Issues page: https://github.com/USGS-R/streamMetabolizer/issues
We can address your issues fastest if they are:
New - search past issues first to see if your question has already been answered. Reopen an old issue if your question was almost but not quite answered.
Complete - share all relevant code and console output/errors/warnings, in the order they were run and produced on your computer. Also include the output from a call to
devtools::session_info()to tell us about your computer's configuration.
Reproducible - include all the data and code necessary for us/others to recreate the problem locally. It's fine to make up data if you can't share yours, as long as the problem still comes through.
Minimal - what is the smallest amount of data and code you can use to demonstrate the problem? This is less essential than the others but improves communication and our response time.
Code of Conduct
We want to encourage a warm, welcoming, and safe environment for contributing to this project. See the code of conduct for more information.
streamMetabolizer was developed 2015-2017 with support from the USGS Powell Center (through a working group on Continental Patterns of Stream Metabolism), the USGS NAWQA program, and the USGS Office of Water Information. Ongoing package work is unfunded and therefore limited, though still enthusiastic.
