In fluxible: Ecosystem Gas Fluxes Calculations for Closed Loop Chamber Setup

quadratic fit to gas concentration over time

Description

fits a quadratic model to the gas concentration over time

Usage

flux_fitting_quadratic(
  conc_df_cut,
  conc_df,
  f_conc,
  f_start,
  f_fluxid,
  start_cut,
  t_zero
)

Arguments

conc_df_cut	dataframe of gas concentration over time, cut
conc_df	dataframe of gas concentration over time
f_conc	column with gas concentration
f_start	column with datetime when the measurement started
f_fluxid	column with ID of each flux
start_cut	time to discard at the start of the measurements (in seconds)
t_zero	time at which the slope should be calculated

Value

a df with the modeled gas concentration, slope, intercept, std error, r square and p value of the quadratic model
