MOSAIC R packages

The various R packages produced by the MOSAIC team.

The following packages are part of the “mosaic suite”. All are available on CRAN and maintained on GitHub.

• {mosaic}

  • {mosaicCore} Contains helper functions. Automatically installed when {mosaic} is installed from CRAN.

• {mosaicData}

• {mosaicCalc} – Completely updated in 2022 to provide better symbolic capabilities while retaining the ease of use of the formula interface. The vignettes give a good introduction to the package. See the Mosaic Calculus textbook for many more examples.

• {ggformula} provides a formula-based interface to the popular ggplot2 graphics system. Some advantages:

  • uses the standard pipe operator (either %>% or the newer |>) instead of the ideosyncratic + of ggplot2.
  • one-liner commands with fewer parentheses: Galton |> gf_point(height ~ mother) compared to Galton |> ggplot2(aes(x=mother, y=height)) + geom_point()
  • Inter-operates with ggplot2() and all related packages.
  • Provides an easy path to learning lm()

• {LST} provides support for the textbook Lessons in Statistical Thinking. {LST} provides highly integrated, introductory-level graphics and modeling in the modern Tidyverse style. Install with remotes::install_github("dtkaplan/LST").

• Deprecated: {mosaicModel} – This package is retained for compatibility with the DataCamp courses on statistical modeling. Many of the features have been transferred to the core mosaic packages listed above.
