Fit Isothermal Holding Data

Description

##TODO

Usage

fit_IsothermalHolding(
  data,
  ITL_model = "GOK",
  rhop,
  plot = TRUE,
  verbose = TRUE,
  txtProgressBar = TRUE,
  trace = FALSE,
  ...
)

Arguments

data	character or data.frame (required): file path or data frame with 5 columns named "SAMPLE", "TEMP", "TIME", "LxTx", "LxTx_ERROR".
ITL_model	character (with default): model to be fitted, either "GOK" or "BTS".
rhop	numeric or RLum.Results (with default): a vector of rho prime values (one for each sample) or an RLum.Results object produced by analyse_FadingMeasurement
plot	logical (with default): enable/disable the plot output.
verbose	logical (with default): enable/disable output to the terminal.
txtProgressBar	logical (with default): enable/disable the progress bar. Ignored if verbose = FALSE.
trace	logical (with default): enable/disable tracing during the nls fitting (minpack.lm::nlsLM).
...	further arguments and graphical parameters that will be passed to the plot function.

Details

Value

The function returns an RLum.Results object and an optional plot. The object returned contains the following elements:

fit	list with the fitted models
coefs	data.frame containing the fitted coefficients for the models
data	data.frame containing the data used in the fitting process

Function version
