R package SSBtools

| SSBtools on CRAN | | pkgdown website | | GitHub Repository | |----------------------|---|----------------------|---|----------------------|

Description

Includes general data manipulation functions, algorithms for statistical disclosure control (Langsrud, 2024) and functions for hierarchical computations by sparse model matrices (Langsrud, 2023).

Installation

You can install SSBtools from CRAN with

install.packages("SSBtools")

Alternatively install from GitHub bydevtools::install_github("statisticsnorway/SSBtools") if you want to test the newest changes.
