## Welcome to the GitHub repository for the invitroTKdata package

The `invitroTKdata` R package contains a collection of datasets
containing a variety of *in vitro* toxicokinetic measurements including
– but not limited to – chemical fraction unbound in the presence of
plasma ($f_{up}$), intrinsic hepatic clearance ($Cl_{int}$), and
membrane permeability for oral absorption (Caco2). The datasets provided
by the package were processed and analyzed with the companion
`invitroTKstats` package

**Notification:** *Datasets within this package have all been processed
with various prototype versions of the `invitroTKstats` R package. We
refer users to the [`invitroTKstats` R
package](https://github.com/USEPA/invitroTKstats) and
[invitrotkstats_dataproc](https://github.com/USEPA/invitrotkstats_dataproc)
GitHub pages to obtain the latest version of the package and original
raw data/processing scripts, respectively.*
