unwrap.CBData {CorrBin} | R Documentation |
unwrap
is a utility function that reformats a CBData or CMData object so
that each row is one observation (instead of one or more clusters). A new
‘ID’ variable is added to indicate clusters. This form can be useful for
setting up the data for a different package.
