Pharmacokinetics of Indomethacin

The Indometh data frame has 66 rows and 3 columns of data on the pharmacokinetics of indometacin (or, older spelling, ‘indomethacin’).




An object of class c("nfnGroupedData", "nfGroupedData", "groupedData", "data.frame") containing the following columns:


an ordered factor with containing the subject codes. The ordering is according to increasing maximum response.


a numeric vector of times at which blood samples were drawn (hr).


a numeric vector of plasma concentrations of indometacin (mcg/ml).


Each of the six subjects were given an intravenous injection of indometacin.

This dataset was originally part of package nlme, and that has methods (including for [,, plot and print) for its grouped-data classes.
