Standart calcul and plot to study paleo and archeo magnetic magnétisation by convention we use the two last character of the variable step to indicate the type of manip example 100RA , 100 is the temperature (step.value) , R is the sens of the magnetisation and A is the name of the step (step.name)

Description

Standart calcul and plot to study paleo and archeo magnetic magnétisation by convention we use the two last character of the variable step to indicate the type of manip example 100RA , 100 is the temperature (step.value) , R is the sens of the magnetisation and A is the name of the step (step.name)

Usage

arai(
  mesures,
  relative = TRUE,
  verbose = TRUE,
  show.plot = TRUE,
  TH = 60,
  aim.coef = 1e-10 * 1e+06,
  step.J0 = "20N0",
  show.step.value = FALSE,
  R.mark = "R",
  V.mark = "V",
  P.mark = "P",
  L.mark = "L",
  Q.mark = "Q",
  pt.col = "blue",
  loop.col = "forestgreen",
  begin.step.value = 0,
  end.step.value = 1000
)

Arguments

mesures	data.frame with the package convention format
relative	plot with a relative value in percent
verbose	show comment
show.plot	display the plot
TH	lab field
aim.coef	used to correct the measurement often 1E-10x1E6 x volume
step.J0	is the step of the natural magnetisation eg "0N0", default 20N0
show.step.value	display on the plot the value of each step
R.mark	= 'R', V.mark = 'V' conventional notation to mark the sens of the magnetisation with the step name
P.mark	= 'P' mark the pTRM check loop
L.mark	= "L", Q.mark = "Q" mark to indiquate the slow cooling step and the quick (fast-normal) cooling step
pt.col	the color of the line and the plot
loop.col	the color of the line showing the the check loop process
begin.step.value	the first step.value (temperature) used to determinate the magnetic field
end.step.value	the last step.value (temperature) used to determinate the magnetic field
