areabiplot (version 1.0.0)
Description
Considering an (n x m) data matrix X, this package is based on the method proposed
by Gower, Groener, and Velden (2010) , 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.
