Generate a fractionation factor object. Can be initialized in alpha
and
epsilon
notation. Fractionation factors can be easily converted from values in one notation to values in
another notation by using switch_notation
.
1 2 3 4 5 6 7 | fractionation_factor(..., major = get_iso_opts("default_major"),
notation = get_iso_opts("default_ff_notation"), ctop = "",
cbot = "", single_as_df = FALSE)
ff(..., major = get_iso_opts("default_major"),
notation = get_iso_opts("default_ff_notation"), ctop = "",
cbot = "", single_as_df = FALSE)

... |
- numeric vectors (can be named) to turn into fractionation factors |
major |
- name of the major isotope in the isotope system [optional] |
notation |
- which notation the value is in, |
ctop |
- name of the compound representing the top isotope ratio [optional] |
cbot |
- name of the compound representing the bottom isotope ratio [optional] |
See isotopia for general information on initializing
and converting to other isotope data objects.
The ff
function is a shorthand for fractionation_factor
but otherwise identical.
Other isotope data types: abundance
,
delta
, intensity
,
ratio
