## Pharmacokinetics of Indomethacin

### Description

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

### Usage

    Indometh

### Format

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

Subject

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

time

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

conc

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

### Details

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 `[`, `as.data.frame`, `plot` and `print`) for its grouped-data classes.
