txtNCA: Text output of NCA for one subject

Description

This is the text form output.

Usage

txtNCA(x, y, dose = 0, adm = "Extravascular", dur = 0, doseUnit = "mg", timeUnit = "h", 
       concUnit = "ug/L", iAUC = "", down="Linear", MW = 0, returnNA = FALSE)

Arguments

x

usually time

y

usually concentration

dose

given amount

adm

one of "Bolus" or "Infusion" or "Extravascular" to indicate drug administration mode

dur

duration of infusion

doseUnit

unit of dose

timeUnit

unit of time

concUnit

unit of concentration

iAUC

interval AUCs to calculate

down

either of "Linear" or "Log" to indicate the way to calculate AUC and AUMC

MW

molecular weight of the drug

returnNA

if returnNA is TRUE, it returns NA values also.
