Synchrony in Motion Energy Analysis (MEA) Time-Series (rMEA)
A suite of tools useful to read, visualize and export bivariate motion energy time-series. Lagged synchrony between subjects can be analyzed through windowed cross-correlation. Surrogate data generation allows an estimation of pseudosynchrony that helps to estimate the effect size of the observed synchronization. Ramseyer & Tschacher (2011) <doi:10.1037/a0023419>.

Tools to Manipulate and Query Semantic Data (rdflib)
The Resource Description Framework, or ‘RDF’ is a widely used data representation model that forms the cornerstone of the Semantic Web. ‘RDF’ represents data as a graph rather than the familiar data table or rectangle of relational databases. The ‘rdflib’ package provides a friendly and concise user interface for performing common tasks on ‘RDF’ data, such as reading, writing and converting between the various serializations of ‘RDF’ data, including ‘rdfxml’, ‘turtle’, ‘nquads’, ‘ntriples’, and ‘json-ld’; creating new ‘RDF’ graphs, and performing graph queries using ‘SPARQL’. This package wraps the low level ‘redland’ R package which provides direct bindings to the ‘redland’ C library. Additionally, the package supports the newer and more developer friendly ‘JSON-LD’ format through the ‘jsonld’ package. The package interface takes inspiration from the Python ‘rdflib’ library.

Single Transferable Vote Counting (STV)
Implementations of the Single Transferable Vote counting system. By default, it uses the Cambridge method for surplus allocation and Droop method for quota calculation. Fractional surplus allocation and the Hare quota are available as options.

Projected Spatial Gaussian Process Methods (psgp)
Implements projected sparse Gaussian process Kriging (Ingram ‘et. al.’, 2008, <doi:10.1007/s00477-007-0163-9>) as an additional method for the ‘intamap’ package.

Fast Polygon to Raster Conversion (fasterize)
Provides a drop-in replacement for rasterize() from the ‘raster’ package that takes ‘sf’-type objects, and is much faster. There is support for the main options provided by the rasterize() function, including setting the field used and background value, and options for aggregating multi-layer rasters. Uses the scan line algorithm attributed to Wylie et al. (1967) <doi:10.1145/1465611.1465619>.
