Fit absorbance data to exponential curve. drm is used for the fitting process.

Description

Fit absorbance data to exponential curve. drm is used for the fitting process.

Usage

abs_fit_slope(
  wl,
  abs,
  lim,
  l_ref = 350,
  control = drmc(errorm = FALSE, noMessage = TRUE),
  ...
)

Arguments

wl	vector containing wavelengths
abs	vector containing absorption in m^-1
lim	vector containing lower and upper limits for wavelengths to use
l_ref	numerical. reference wavelength, default is 350, if set to NA l_ref is fitted
control	control parameters for drm, see drmc
...	parameters that are passed on to drm

Value

numeric exponential slope coefficient
