This function performs NCA analysis using the PKNCA package for multiple analytes in a NIF object. It uses analyte-specific grouping in the concentration and dose formulas.

Usage

nca2(
  obj,
  analytes = NULL,
  parameters = NULL,
  keep = NULL,
  average_duplicates = TRUE
)

Arguments

obj

A NIF object containing concentration-time data

analytes

Optional vector of analytes to analyze. If NULL, all analytes will be analyzed.

parameters

Optional vector of PK parameters to calculate. If NULL, default parameters will be used.

keep

Optional vector of additional columns to keep in the output.

average_duplicates

Boolean to indicate whether duplicate entries should be averaged.

Value

A data frame containing NCA results
