Provides basic access in an R session to Csound
<http://www.csounds.com>, a powerful free and open-source
software sound synthesizer. The package functionality is
largely geared towards supporting the needs of the playitbyr
package for sonification and is not particularly mature on its
own. But it certainly can be used without knowing anything
about playitbyr.
Csound (>= 5), available at
<http://csound.sourceforge.net/>. This package uses the shared
library file, which is included with standard Mac and Windows
installations of Csound.  Some Linux distributions package the
library file separately from the executible, so for instance on
Debian and Ubuntu you would need the "libcsound64-dev" package.
See the package web site for more guidance on setup and
configuration.

Correlates of State Policy Data Set in R
Provides the Correlates of State Policy data set for easy use in R.

Complete Discrete Fourier Transform (DFT) and Periodogram
Calculate the predictive discrete Fourier transform, complete discrete Fourier transform, complete periodogram, and tapered complete periodogram. This algorithm is based on the preprint "Spectral methods for small sample time series: A complete periodogram approach" (2020) by Sourav Das, Suhasini Subba Rao, and Junho Yang.

A Tool for the Correlates of State Policy Project Data
Caleb Lucas (https://caleblucas.com/) and Joshua McCrain (http://joshuamccrain.com/)
A tool that imports, subsets, visualizes, and exports the Correlates of State Policy Project dataset assembled by Marty P. Jordan and Matt Grossmann (2020) <http://ippsr.msu.edu/public-policy/correlates-state-policy>. The Correlates data contains over 2000 variables across more than 100 years that pertain to state politics and policy in the United States. Users with only a basic understanding of R can subset this data across multiple dimensions, export their search results, create map visualizations, export the citations associated with their searches, and more.
