Dear all, I have a Pharmokinetics data set where single dose is used for several time points on 8 subjects. I wanted to fit a two compartment model on the data set to see whether it is reasonable. This is the first time to analyze a PK data set and am not familar with various concepts in the compartment models. It seems that PK.fit function in the PK.fit package can be used to fit compartment models. However when I looked up the help file, it does not seem to have any examples and or any other kind of help. Can anyone familiar with this give some hint on the reference of fitting compartment models in R. Thank you very much. Hanna [[alternative HTML version deleted]]
