convert_absorbance: convert_absorbance

In mirkko-hub/jasco2: Handling of Jasco Spectrophotometer data

Description

given a tibble containing a column 'Absorbance', the concentration of a chemical of which the Absorbance is measured is calculated and attached to the tibble. Userprovided coefficients return the calculated concentration in corresponding units - If the coefficient is one of the chemicals provided in 'chemical_specs.R' the calculated concentration is stated in mol/l .

Usage

convert_absorbance(data, coef)

Arguments

data	a tibble with at least one column 'Absorbance'.
coef	either the name of any chemical found in 'chemicals_specs' or a user-provided appropriate absorption coefficient (a named vector, eg. 'setNames(7282, "chemical1")')

Examples

# this is a typical output from jasco_tibble
jasco_df

jasco_df %>%
  convert_absorbance(., "NADH")
  
jasco_df %>%
  convert_absorbance(., coef = setNames(7282, "chemical XYZ"))
