Millications

Description

Returns millications.

Usage

millications(x,print=FALSE,save=FALSE)

Arguments

x

matrix or vector with major-element data

print

logical: print the result?

save

logical: should be the results assigned globally?

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.
