millications {GCDkit} | R Documentation |
Returns millications.
millications(x=WR,print=TRUE,save=FALSE,precision=getOption("gcd.digits"))
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. |
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
Numeric matrix (or vector) with the millications. If 'save=TRUE
',
'results
' and 'milli
' are assigned globally.
