Choose how to interpolate, extrapolate, or integrate data in each concentration interval

Usage

choose_interval_method(conc, time, tlast, method, auc.type, options)

Arguments

conc: Measured concentrations
time: Time of the measurement of the concentrations
tlast: Time of last concentration above the limit of quantification (will be calculated, if not provided)
method: The method for integration (one of 'lin up/log down', 'lin-log', or 'linear')
auc.type: The type of AUC to compute. Choices are 'AUCinf', 'AUClast', and 'AUCall'.
options: List of changes to the default PKNCA options (see PKNCA.options())

Value

A character vector of methods for interpolation/extrapolation methods that is the same length as conc which indicates how to interpolate/integrate between each of the concentrations (all but the last value in the vector) and how to extrapolate after tlast (the last item in the vector). Possible values in the vector are: 'zero', 'linear', 'log', and 'extrap_log'
