Tools for data importation, recoding, and inspection.
    There are functions to create new project
    folders, R code templates, create uniquely named output
    directories, and to quickly obtain a visual summary for each
    variable in a data frame.  The main feature here is the systematic
    implementation of the "variable key" framework for data
    importation and recoding.  We are eager to have community feedback
    about the variable key and the vignette about it. In version 1.7,
    the function 'semTable' is removed. It was deprecated since 1.67.
    That is provided in a separate package, 'semTable'.

The format KVH is a lightweight format that can be read/written both by humans and machines.
   It can be useful in situations where XML or alike formats seem to be an overkill.
   We provide an ability to parse KVH files in R pretty fast due to 'Rcpp' use.

Access business registration data from the Dutch Chamber of
    Commerce (Kamer van Koophandel, KvK) through their official API
    <https://developers.kvk.nl/>. Search for companies by name, location,
    or registration number. Retrieve detailed business profiles,
    establishment information, and company name histories. Built on
    'httr2' for robust API interaction with automatic pagination, error
    handling, and usage tracking.

Helper functions for creating formatted summary of regression models, writing publication-ready tables to latex files, and running Monte Carlo experiments.

Time Series Analysis including break detection, spectral analysis, KZ Fourier Transforms.

A spatial smoothing algorithm based on convolutions of finite rectangular kernels that provides sharp resolution in the presence of high levels of noise.

An efficient procedure for feature selection for generalized linear models with L0 penalty, including linear, logistic, Poisson, gamma, inverse Gaussian regression. Adaptive ridge algorithms are used to fit the models.

Highly optimized toolkit for approximately solving L0-regularized learning problems (a.k.a. best subset selection).
    The algorithms are based on coordinate descent and local combinatorial search.
