Simultaneous Inference for Multiple Linear Contrasts in GEE Models
Provides global hypothesis tests, multiple testing procedures and simultaneous confidence intervals for multiple linear contrasts of regression coefficients in a single generalized estimating equation (GEE) model or across multiple GEE models. GEE models are fit by a modified version of the 'geeM' package.
Multivariate Polynomials with Rational Coefficients
Symbolic calculation and evaluation of multivariate
polynomials with rational coefficients. This package is strongly
inspired by the 'spray' package. It provides a function to
compute Gröbner bases (reference
Read and Write CSV on the Web (CSVW) Tables and Metadata
Provide functions for reading and writing CSVW - i.e. CSV tables and JSON metadata. The metadata helps interpret CSV by setting the types and variable names.
Estimate Parameters in the Generalized SBM
Given an adjacency matrix drawn from a Generalized Stochastic Block Model with missing observations, this package robustly estimates the probabilities of connection between nodes and detects outliers nodes, as describes in Gaucher, Klopp and Robin (2019)
Plot Functions for Use in Bibliometrics
Currently, the package provides several functions for plotting and analyzing bibliometric data (JIF, Journal Impact Factor, and paper percentile values), beamplots with citations and percentiles, and three plot functions to visualize the result of a reference publication year spectroscopy (RPYS) analysis performed in the free software 'CRExplorer' (see < http://crexplorer.net>). Further extension to more plot variants is planned.
Discrete Multivariate Probability Distributions
Provides an object class for dealing with many multivariate probability distributions at once, useful for simulation.
Linear, Quadratic, and Rational Optimization
Solver for linear, quadratic, and rational programs with linear, quadratic, and rational constraints. A unified interface to different R packages is provided. Optimization problems are transformed into equivalent formulations and solved by the respective package. For example, quadratic programming problems with linear, quadratic and rational constraints can be solved by augmented Lagrangian minimization using package 'alabama', or by sequential quadratic programming using solver 'slsqp'. Alternatively, they can be reformulated as optimization problems with second order cone constraints and solved with package 'cccp'.
Interface Between R and the OpenStreetMap-Based Routing Service OSRM
An interface between R and the 'OSRM' API. 'OSRM' is a routing service based on 'OpenStreetMap' data. See < http://project-osrm.org/> for more information. This package enables the computation of routes, trips, isochrones and travel distances matrices (travel time and kilometric distance).
Clear and Condense Argument Check for User-Defined Functions
A concise check of the format of one or multiple input arguments (data type, length or value) is provided. Since multiple input arguments can be tested simultaneously, a lengthly list of checks at the beginning of your function can be avoided, hereby enhancing the readability and maintainability of your code.
Translation of Base R-Like Functions for 'data.table' Objects
Some heavily used base R functions are reconstructed to also be compliant to data.table objects. Also, some general helper functions that could be of interest for working with data.table objects are included.
