This vignette describes related resources and materials useful for teaching statistics with a focus on modeling and computation.

## Package Vignettes

The `mosaic` package includes a number of vignettes. These are available from within R, from cran.r-project.org/package=mosaic, or from www.mosaic-web.org/mosaic/.

- Minimal R describes a minimal set of R commands for use in Introductory Statistics and discusses why it is important to keep the set of commands small;

- Resampling methods in R demonstrates how to use the `mosaic` package to compute p-values for randomization tests and bootstrap confidence intervals in a number of common situations. The examples are based on the ``resampling bake off’’ at USCOTS 2011.

- ggformula/lattice conversion examples compares the lattice and ggformula formula interfaces for creating graphics.

- Less Volume, More Creativity, based on slides from an ICOTS 2014 workshop, introduces the `mosaic` package and related tools and describes some of the philosophy behind the design choices made in the `mosaic` package.

- Graphics with the mosaic package is gallery of plots made using tools from the `mosaic` package.

## Auxiliary packages

Some features of the mosaic package are provided through auxiliary packages. These include:

- mosaicModel – implements high-level systems for working with statistical models: effect-size calculation, bootstrapped confidence intervals, prediction error, graphics for models with multiple inputs. The package contains an introductory vignette.
- mosaicCalc – provides the calculus components of mosaic, including integration, differentiation, and differential equation solving.

Install these packages using `install.packages(c("mosaicCalc", "mosaicModel"))`.

Pruim R, Kaplan DT and Horton NJ (2017). The mosaic Package: Helping Students to ‘Think with Data’ Using R. The R Journal, 9(1), pp. 77-102. https://journal.r-project.org/articles/RJ-2017-024/index.html.

Abstract: The mosaic package provides a simplified and systematic introduction to the core functionality related to descriptive statistics, visualization, modeling, and simulation-based inference required in first and second courses in statistics. This introduction to the package describes some of the guiding principles behind the design of the package and provides illustrative examples of several of the most important functions it implements. These can be combined to help students ‘think with data’ using R in their early course work, starting with simple, yet powerful, declarative commands.

- Foundations and Applications of Statistics: An Introduction Using R (R Pruim, second edition) is an R-infused probability and mathematical statistics text that emphasizes connections between probability and statistics. The first edition of the book predates the `mosaic` package, but much of the code originally in the `fastR` package has been moved into the `mosaic` package. The second edition is supported by the `fastR2` package and uses `ggformula` for plotting.
