R package VGAMdata. Data sets to accompany the VGAM package and the book ”Vector Generalized Linear and Additive Models: With an Implementation in R” (Yee, 2015) &lt;<a href=””>doi:10.1007/978-1-4939-2818-7</a>&gt;. 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).
