Millications

Description

Returns millications.

Usage

millications(x=WR,print=TRUE,save=FALSE,precision=getOption("gcd.digits"))

Arguments

x

matrix or vector with major-element data

print

logical: print the result?

save

logical: should be the results assigned globally?

precision

precision of the result.

Details

The millications are used for many plots of the French school, e.g. De la Roche et al. (1980) or Debon & Le Fort (1983, 1988).
The calculated values are Si, Ti, Al, Fe3, Fe2, Fe, Mn, Mg, Ca, Na, K, P.

Element[i] = 1000 (Oxide[i] (wt. %)) / (MW(Oxide[i]) * (x(Element[i]) )

Where: MW = molecularWeight of the Oxide[i], x = number of atoms of Element[i] in its formula

Value

Numeric matrix (or vector) with the millications. If 'save=TRUE', 'results' and 'milli' are assigned globally.
