Analysis of dyadic network and relational data using additive and
    multiplicative effects (AME) models. The basic model includes
    regression terms, the covariance structure of the social relations model
    (Warner, Kenny and Stoto (1979) <DOI:10.1037/0022-3514.37.10.1742>, 
    Wong (1982) <DOI:10.2307/2287296>), and multiplicative factor
    models (Hoff(2009) <DOI:10.1007/s10588-008-9040-4>). 
    Several different link functions accommodate different
    relational data structures, including binary/network data, normal
    relational data, zero-inflated positive outcomes using a tobit model, ordinal relational data and data from
    fixed-rank nomination schemes. Several of these link functions are
    discussed in Hoff, Fosdick, Volfovsky and Stovel (2013) 
    <DOI:10.1017/nws.2013.17>. Development of this
    software was supported in part by NIH grant R01HD067509.

A color palette generator inspired by American politics, with colors ranging from blue on the 
    left to gray in the middle and red on the right. A variety of palettes allow for a range of applications 
    from brief discrete scales (e.g., three colors for Democrats, Independents, and Republicans) to 
    continuous interpolated arrays including dozens of shades graded from blue (left) to red (right). This
    package greatly benefitted from building on the source code (with permission) from Ram and Wickham (2015).

Raw and processed versions of the data from De Cock (2011) <http://ww2.amstat.org/publications/jse> are included in the package.

A collection of lightweight functions that can be used to
    determine the computing environment in which your code is running.
    This includes operating systems, continuous integration (CI)
    environments, containers, and more.

Modern software often poorly support older file formats. This
    package intends to handle many file formats that were native to the
    antiquated Commodore Amiga machine. This package focuses on file types from
    the older Amiga operating systems (<= 3.0). It will read and write specific
    file formats and coerces them into more contemporary data.
