gasanalyzer

gasanalyzer streamlines photosynthesis data workflows by importing, preprocessing, and analyzing data from portable gas analyzers to facilitate reproducible research and sensitivity analyses.

Key Features:

• Data Import: The package provides methods to import data from different portable gas-exchange instruments.
• Standardized Nomenclature: The package translates photosynthetic variables to a standardized nomenclature.
• Recalculation of Derived Quantities: The package optionally recalculates derived quantities using standardized equations based on underlying physical models.
• Sensitivity Analysis: The package facilitates performing sensitivity analyses on variables or assumptions used in the calculations to allow researchers to better assess the robustness of results.

Scientific Applications:

• Plant (Eco-)Physiology Research: The package supports the analysis of photosynthetic traits that are calculated from combinations of direct measurements.
• Reproducible Photosynthesis Data Analysis: The package enables fully scripted workflows for importing, pre-processing, and recalculating derived quantities from gas-exchange data.
• Cross-Instrument Data Comparison: The package addresses differences in definitions and assumptions across commercially available gas-exchange instruments by standardizing calculations.

Methodology:

The package imports data from different instruments, translates photosynthetic variables to standardized nomenclature, and optionally recalculates derived quantities using standardized equations based on underlying physical models with additional constants or assumed values.
