Accesses raw data via API and calculates social
    determinants of health measures for user-specified locations in the
    US, returning them in tidyverse- and sf-compatible data frames.

Provides an interface to search, read, query, and retrieve metadata for 
    datasets hosted on 'Socrata' open data portals. Supports all 'Socrata' data types, 
    including spatial data returned as 'sf' objects.

Supporting materials for a course and book on data visualization. It contains utility functions for graphs and several sample data sets. See Healy (2019) <ISBN 978-0691181622>.

Variable and interaction selection are essential to classification in high-dimensional setting. In this package, we provide the implementation of SODA procedure, which is a forward-backward algorithm that selects both main and interaction effects under logistic regression and quadratic discriminant analysis. We also provide an extension, S-SODA, for dealing with the variable selection problem for semi-parametric models with continuous responses.

Bindings to 'libsodium' <https://doc.libsodium.org/>: a modern, 
    easy-to-use software library for encryption, decryption, signatures, password
    hashing and more. Sodium uses curve25519, a state-of-the-art Diffie-Hellman 
    function by Daniel Bernstein, which has become very popular after it was 
    discovered that the NSA had backdoored Dual EC DRBG.

Provides an interface to the 'NoSQL' database 'CouchDB'
    (<http://couchdb.apache.org>). Methods are provided for managing
    databases within 'CouchDB', including creating/deleting/updating/transferring,
    and managing documents within databases. One can connect with a local
    'CouchDB' instance, or a remote 'CouchDB' databases such as 'Cloudant'. 
    Documents can be inserted directly from vectors, lists, data.frames, 
    and 'JSON'. Targeted at 'CouchDB' v2 or greater.
