read_dual_pam_data: Read and Process DualPAM Data

In pam: Fast and Efficient Processing of PAM Data

Read and Process DualPAM Data

Description

Reads raw CSV files generated by DualPAM software, calculates electron transport rate (ETR) values, and returns a cleaned dataset. Customization may be needed for non-DualPAM devices.

Usage

read_dual_pam_data(
  csv_path,
  remove_recovery = TRUE,
  etr_factor = 0.84,
  fraction_photosystem_I = 0.5,
  fraction_photosystem_II = 0.5
)

Arguments

csv_path	File path to the CSV file.
remove_recovery	Logical. Removes recovery measurements if TRUE. Default is TRUE.
etr_factor	Numeric. Factor for ETR calculation. Default is 0.84.
fraction_photosystem_I	Numeric. Relative distribution of absorbed PAR to photosystem I. Default is 0.5.
fraction_photosystem_II	Numeric. Relative distribution of absorbed PAR to photosystem II. Default is 0.5.

Details

Calculates ETR using:

\text{ETR} = \text{PAR} \cdot \text{ETR-Factor} \cdot \text{Fraction of Photosystem (I or II)} \cdot \text{Yield (I or II)}

Value

A 'data.table' with processed data and calculated ETR values.
