Configuration management using files (YAML, JSON, INI, TXT),
  JSON strings, and command line arguments. Command line arguments
  can be used to override configuration. Period-separated command line
  flags are parsed as hierarchical lists. Environment variables, R global variables,
  and configuration values can be substituted.

Solve some conic related problems (intersection of conics with lines and conics, arc length of an ellipse, polar lines, etc.).

'TROLL' is coded in C++ and it typically simulates hundreds of
    thousands of individuals over hundreds of years. The 'rcontroll' R package 
    is a wrapper of 'TROLL'. 'rcontroll' includes functions that generate inputs 
    for simulations and run simulations. Finally, it is possible to analyse 
    the 'TROLL' outputs through tables, figures, and maps taking advantage of 
    other R visualisation packages. 'rcontroll' also offers the possibility to 
    generate a virtual LiDAR point cloud that corresponds to a snapshot of 
    the simulated forest.

A collection of small text corpora of interesting data.
    It contains all data sets from 'dariusk/corpora'. Some examples:
    names of animals: birds, dinosaurs, dogs; foods: beer categories,
    pizza toppings; geography: English towns, rivers, oceans;
    humans: authors, US presidents, occupations; science: elements,
    planets; words: adjectives, verbs, proverbs, US president quotes.

Bundles the datasets and functions featured in Philip H. 
    Pollock and Barry C. Edwards<https://edge.sagepub.com/pollock>, "An R Companion to Political Analysis, 3rd Edition," Thousand Oaks, CA: Sage Publications.

R interface to CPLEX solvers for linear, quadratic, and (linear and quadratic) mixed integer programs. Support for quadratically constrained programming is available. See the file "INSTALL" for details on how to install the Rcplex package in Linux/Unix-like and Windows systems. Support for sparse matrices is provided by an S3-style class "simple_triplet_matrix" from package slam and by objects from the Matrix package class hierarchy.
