conc |
Concentration measured |
time |
Time of concentration measurement (must be monotonically increasing and the same length as the concentration data) |
start, end |
The start and end of the interval |

ignored |
options |
List of changes to the default |
max_shift |
The maximum amount of time to shift a concentration forward
(defaults to 5% of the interval duration, i.e. |
A data.frame with one column named conc with imputed concentrations and one column named time with the times.
PKNCA_impute_method_start_conc0()
: Add a new concentration of 0 at the start
time, even if a nonzero concentration exists at that time (usually used
with single-dose data)
PKNCA_impute_method_start_cmin()
: Add a new concentration of the minimum during
the interval at the start time (usually used with multiple-dose data)
PKNCA_impute_method_start_predose()
: Shift a predose concentration to become the
time zero concentration (only if a time zero concentration does not exist)
