d13C.to.D13C: d13C.to.D13C

In isocalcR: Isotope Calculations in R

d13C.to.D13C

Description

Calculates leaf carbon isotope discrimination given plant tissue d13C signature.

Usage

d13C.to.D13C(d13C.plant, year, frac = 0)

Arguments

d13C.plant	Measured plant tissue carbon isotope signature, per mille (‰)
year	Year to which the sample corresponds
frac	Post-photosynthetic fractionation factor, defaults to 0 assuming leaf material with no post-photosynthetic fractionation. User should supply reasonable value if leaf fractionation present or if samples are from wood (generally -1.9 - -2.1).

Value

Carbon isotope discrimination in units of per mille (‰).
