Method "popline" for Classes "oneAgeTest" and "ageTests"

Description

Display observations as well as their reference's population as calculated by the function tests() given their value of Pb (ppm) and Th*(ppm), where Th* is a function of Th and U variables.

Usage

## S4 method for signature 'oneAgeTest'
popline(x, main2 = "")

Arguments

x

an object of class "oneAgeTest" or "ageTests" (see section Methods)

main2

a character string, title of the plot

Details

Th* is computed thanks to the following formula: Th + 232*U * [238(exp(4.9475*10^{-5}*Age) - 1)]^{-1} * [[exp(9.8485*10^{-4}*Age + 138*exp(1.55125*10^{-4}*Age))][139] - 1]

Slopes, depending directly of the ages computed with the function tests(), are obtained through the following equation: [exp(4.9475*10^{-5}*Age) - 1] * 207.3/232.

Usage

popline(x, main2)

Methods

  • signature(object = "oneAgeTest"): an object of type oneAgeTest as produced by the function tests().

  • main2: a character string to entitle the plot

  • signature(object = "ageTests"): an object of type ageTests as produced by the function tests().

  • main2: a character string to entitle the plot
