PhotoGEA (short for photosynthetic gas exchange analysis) is an R package that provides a suite of tools for loading, processing, and analyzing photosynthetic gas exchange data. See Lochocki, Salesse-Smith, & McGrath (2025) for more information.
PhotoGEA is available on CRAN, so the easiest way to
install the latest release is to type the following from within an R
terminal:
install.packages('PhotoGEA')See the Frequently Asked Questions for alternative installation methods.
The best way to learn about using PhotoGEA is to visit
the PhotoGEA
website and click the Get
started link in the top menu bar. The website includes documentation
for all the functions and data sets included in the package, as well as
articles that describe its general features and several important use
cases.
The PhotoGEA Publications page includes links to publicly-available analysis scripts that have been used for peer-reviewed publications. These may be a useful source of ideas.
Several example scripts are also provided in the
example_scripts directory of the source code repository.
To run one of these scripts, set the working directory to a folder that
contains a local copy of the script and use the source
command to execute the code in the script. No guarantees are made that
these scripts will run on your machine or be compatible with your data,
but they may also be a useful source of ideas.
The PhotoGEA R package, its documentation, and its
associated example scripts are licensed under the MIT license.
These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
