math/R-VGAMdata: import R-VGAMdata-1.1.12

Mainly data sets to accompany the VGAM package and the book "Vector
Generalized Linear and Additive Models: With an Implementation in R"
(Yee, 2015) <DOI:10.1007/978-1-4939-2818-7>. These are used to
illustrate vector generalized linear and additive models
(VGLMs/VGAMs), and associated models (Reduced-Rank VGLMs, Quadratic
RR-VGLMs, Row-Column Interaction Models, and constrained and
unconstrained ordination models in ecology). This package now contains
some old VGAM family functions which have been replaced by newer ones
(often because they are now special cases).
