If the concentrations or times are invalid, will provide an error. Reasons for being invalid are
time is not a number
conc is not a number
Any time value is NA
time is not monotonically increasing
conc and time are not the same length
check.conc.time(conc, time, monotonic.time = TRUE)
| conc | Measured concentrations |
|---|---|
| time | Time of the measurement of the concentrations |
| monotonic.time | Must the time be unique and monotonically increasing? |
None
Some cases may generate warnings but allow the data to proceed.
A negative concentration is often but not always an error; it will generate a warning.
