It can contain the following entries: content The name of the column describing sample content. concentration The name of the column containing the concentration series. fret_channel The name of the column containing fluorescence intensities from the FRET channel. acceptor_channel The name of the column containing fluorescence intensities from the acceptor channel. donor_channel The name of the column containing fluorescence intensities from the donor channel. titration The name describing points of the titration series. acceptor_only The name describing points of the control series with only acceptor. donor_only The name describing points of the control series with only donor. buffer_only The name describing points of the control series with only buffer. parallel The name of the column containing fluorescence intensities from the parallel polarization plane. perpendicular The name of the column containing fluorescence intensities from the perpendicular polarization plane. polarization The name of the column containing fluorescence polarization. anisotropy The name of the column containing fluorescence anisotropy. intensity The name of the column containing fluorescence intensity. baseline The name describing points of the baseline series in a fluorescence polarization or anisotropy dataset.

Value

An invisible copy of the original environment containing default metadata. As a side effect, updates the column and sample names in the package-wide environment.
