default_ab_notation |
default notation of abundance objects,

default_ff_notation |
default notation of fractionation factors |
default_delta_notation |
default notation of delta values |
default_intensity_unit |
default unit for intensity values |
default_major |
default major isotope on all isotope objects |
exact_mass_balance |
NOT IMPLEMENTED YET!
If enabled, mass balance calculations with delta values (i.e. If disabled, mass balance calculations with delta values ( see |
standards |
isotope ratio objects to register as standards |
default |
minor default minor isotope on all isotope objects |
get_iso_opts
allows retrieval of all or individual isotopia options.
Returns a single value if only one option is requested, a named list if multiple
Default options are the following and are set during package loading together
with the default standards
set_iso_opts(
default_ab_notation = "raw",
default_ff_notation = "alpha",
default_delta_notation = "permil",
default_intensity_unit = "",
default_major = "",
default_minor = "",
exact_mass_balance = FALSE
)
Other options: register_standard
1 2 3 | get_iso_opts("standards") # get a table of all standards
get_iso_opts(c("default_major", "default_minor")) # get a named list with the
default major and minor isotopes
