%description
Considering an (n x m) data matrix X, this package is based on the method
proposed by Gower, Groener, and Velden (2010)
<doi:10.1198/jcgs.2010.07134>, and utilize the resulting matrices from the
extended version of the NIPALS decomposition to determine n triangles
whose areas are used to visually estimate the elements of a specific
column of X. After a 90-degree rotation of the sample points, the
triangles are drawn regarding the following points: 1.the origin of the
axes; 2.the sample points; 3. the vector endpoint representing some
variable.
