getJfactors: Calculate the irradiation parameter ('J factor')

In ArArRedux: Rigorous Data Reduction and Error Propagation of Ar40 / Ar39 Data

Description

Interpolate the irradiation parameters for the samples given the 40Ar*/39ArK ratios of the samples and fluence monitors

Usage

getJfactors(R)

Arguments

R	a vector of 40Ar*/39ArK ratios

Value

an object of class redux containing, as intercepts, the 40Ar*/39ArK ratios of the samples, the interpolated J-factors, and the 40K decay constant; and as covmat: the covariance matrix. All other class properties are inherited from R.

Examples

data(Melbourne)
R <- get4039(Melbourne$X,Melbourne$irr)
J <- getJfactors(R)
plotcorr(J)

Example output

Warning message:
In stats::cov2cor(X$covmat) :
  diag(.) had 0 or NA entries; non-finite result is doubtful
