ratio: Isotope ratio
In isoverse/isotopia: Work with Isotopic Data in R

Description Usage Arguments See Also Examples

Generate isotope ratio objects. See isotopia for general information on initializing and converting isotope data objects.

1 2	ratio(..., major = get_iso_opts("default_major"), compound = "", weight = numeric(), single_as_df = FALSE)

`...`	- numeric vectors (can be named) to turn into isotope ratio objects
`major`	- name of the major isotope in the single ratio or isotope system [optional]
`compound`	- name of the compound the isotopic values belong to [optional]
`weight`	- weight the isotope value (with a mass, concentration, etc.) for easy mass balance calculations. The default value is 1, i.e. an unweighted isotope value. If specified, `weight` must be a single value or a numeric vector of the same size as the data values. The weight of an isotope value obejct can be retrieved and (re)set with the `weight` function.

Other isotope data types: abundance, delta, fractionation_factor, intensity

ratio(0.1) # single value
ratio(c(0.1, 0.2, 0.3)) # multiple values
ratio(`13C` = c(0.1, 0.2, 0.3)) # named ratio
ratio(`33S` = c(0.1, 0.2, 0.3), `34S` = c(0.2, 0.4, 0.6), major = "32S") # isotope system
