crimerate

Zone_climTUN

The <code>crimerate</code> dataset provides crime rates per 100,000 people in
 seven categories for each of the fifty states (USA) in 1977. The <code>timage12</code> dataset
 is an image from fMRI analysis (one brain slice), it is a t-statistic image over 12 subjects of the activation (verbal) parameter.
 The <code>Zone_climTUN</code> is an object of class Map representing montly (<code>12</code>) measurements in Tunisia 
of <code>10</code> climatic indicators. The grid of <code>2599</code> cells was stored previously as a shapefile and read using <code>read.shape</code>.

datasets

A multiway method to decompose a tensor (array) of any
        order, as a generalisation of SVD also supporting non-identity
        metrics and penalisations. 2-way SVD with these extensions is
        also available. The package includes also some other multiway
        methods: PCAn (Tucker-n) and PARAFAC/CANDECOMP with these
        extensions.
