quality assessment for the slopes estimated by flux_fitting
Source:R/flux_quality_exp.R
flux_quality_exp.Rdindicates if fluxes should be discarded or replaced by 0 according to parameters set by user. flux_quality_lm is for the model of the lm family. flux_quality_exp is for the exponential model.

)Arguments
- slopes_df
dataset containing slopes, fluxID, and parameters of the exponential expression
- conc_col
column with gas concentration
- f_fluxid
column of ID for each measurement
- f_slope
column containing the slope of each flux (as calculated by the flux_fitting function)
- f_time
column containing the time of each measurement in seconds
- f_fit
column containing the modeled data
- f_cut
column containing the cutting information
- f_b
column containing the b parameter of the exponential expression
- force_discard
vector of fluxIDs that should be discarded by the user's decision
- force_ok
vector of fluxIDs for which the user wants to keep the calculated slope despite a bad quality flag
- force_zero
vector of fluxIDs that should be replaced by zero by the user's decision
- rmse_threshold
threshold for the RMSE of each flux above which the fit is considered unsatisfactory
- cor_threshold
threshold for the correlation coefficient of gas concentration with time below which the correlation is considered non significant
- b_threshold
threshold for the b parameter. Defines a window with its opposite inside which the fit is considered good enough.
