Wrapper for the 'PoetryDB' API <http://poetrydb.org> that allows for interaction and data extraction from the 
  database in an R interface. The 'PoetryDB' API is a database of poetry and poets implemented with 'MongoDB' to 
  enable developers and poets to easily access one of the most comprehensive poetry databases currently available.

Visualizations to explain the results of a topological
  data analysis. The goal of topological data analysis is to identify
  persistent topological structures, such as loops (topological circles)
  and voids (topological spheres), in data sets. The output of an
  analysis using the 'TDA' package is a Rips diagram (named after the
  mathematician Eliyahu Rips). The goal of 'RPointCloud' is to fill in
  these holes in the data by providing tools to visualize the features
  that help explain the structures found in the Rips diagram. See McGee
  and colleagues (2024) <doi:10.1101/2024.05.16.593927>.

Collection of tools to calculate portfolio performance metrics. Portfolio performance is a key measure for investors. These metrics are important to analyse how effectively their money has been invested. This package uses portfolio theories to give investor tools to evaluate their portfolio performance.

Provides an interface between R and 'PostGIS'-enabled
    'PostgreSQL' databases to transparently transfer spatial
    data. Both vector (points, lines, polygons) and raster data are
    supported in read and write modes. Also provides convenience
    functions to execute common procedures in 'PostgreSQL/PostGIS'.

Fully DBI-compliant C++-backed interface to PostgreSQL
    <https://www.postgresql.org/>, an open-source relational database.
