Count the number of concentration measurements in an interval

count_conc is typically used for quality control on the data to ensure that there are a sufficient number of non-missing samples for a calculation and to ensure that data are consistent between individuals.

Usage

pk.calc.count_conc(conc, check = TRUE)

Arguments

conc

Measured concentrations

check

Run assert_conc()?

Value

a count of the non-missing concentrations (0 if all concentrations are missing)
