fractionation {ArArRedux} | R Documentation |
Compute the mass fractionation correction
Description
Compares the measured 40Ar/36Ar ratio of an air shot on a given detector with the atmospheric ratio.
Usage
fractionation(fname, detector, MS = "ARGUS-VI", PH = FALSE)
Arguments
fname |
a .csv file with the air shot data |
detector |
the name of the ion detector |
MS |
the type of mass spectrometer |
PH |
TRUE if the data were recorded in 'peak hopping' mode, FALSE if recorded in multicollector mode. |
Value
an object of class logratios
Examples
data(Melbourne)
fd37file <- system.file("AirL2.csv",package="ArArRedux")
fd40file <- system.file("AirH1.csv",package="ArArRedux")
fract <- list(fractionation(fd37file,"L2",PH=TRUE),
fractionation(fd40file,"H1",PH=FALSE))
if (isTRUE(all.equal(Melbourne$fract,fract))){
print("We just re-created the fractionation correction for the Melbourne dataset")
}
