refold

Performing to matrices tensorisation, which is the inverse process of unfolding

To handle higher-order tensor data. See Kolda and Bader (2009) <doi:10.1137/07070111X> for details on tensor. While existing packages on tensor data extend the base 'array' class to some data classes, this package serves as an alternative resort to handle tensor only as 'array' class.
Some functionalities related to missingness are also supported.
