Fractionate an isotopic value

This function calculates the outcome of isotopic fractionation by a fractionation_factor and can be applied to ratio data, delta values or other fractionation_factor objects.

fractionate(frac, delta)
fractionate(delta, frac)
fractionate(frac, ratio)

# S4 method for ANY,ANY
fractionate(frac, iso)

# S4 method for FractionationFactor,Ratio
fractionate(frac, iso)

# S4 method for FractionationFactor,FractionationFactor
fractionate(frac, iso)

# S4 method for FractionationFactor,Delta
fractionate(frac, iso)

# S4 method for Delta,FractionationFactor
fractionate(frac, iso)

Arguments

frac	the fractionation factor ff used to fractionate the isotope value
delta	isotope object to fractionate
ratio	isotope object to fractionate

Value

an object of the same type as the isotope object that gets fractionated

Note

Several of these calculations are also implemented with an arithmetic shorthand. All calculatinos are only permissible if the fractionation factors and isotope values have matching attributes.
