Determine the last observed concentration above the limit of quantification (LOQ).

If all concentrations are missing, NA_real_ is returned. If all concentrations are zero (below the limit of quantification) or missing, zero is returned. If Tlast is NA (due to no non-missing above LOQ measurements), this will return NA_real_.

Usage

pk.calc.clast.obs(conc, time, check = TRUE)

Arguments

conc

Measured concentrations

time

Time of the measurement of the concentrations

check

Run assert_conc_time()?

Value

The last observed concentration above the LOQ
