Details

Many of the functions for logspline, oldlogspline, lspec, polyclass, hare, heft, and polymars were written in the ``before data.frame'' era; unstrip attempts to keep all these functions useful with more advanced input objects. In particular, many of these functions call unstrip before doing anything else.

Examples

data(co2)
unstrip(co2)
data(iris)
unstrip(iris)
