This document is intended to help users of the
mosaic package migrate their
lattice package graphics to
ggformula. 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.
mosaic package used
lattice graphics but now support is also available for the improved
ggformula system. Going forward,
ggformula will be the preferred graphics package for Project MOSAIC.
We can use stacked layers to add a density curve based on a maximum likelihood fit or a kernel density estimate (see also
### Density over histograms (lattice)
mosaic makes it easy to add a fitted distribution to a histogram.
Within RStudio, after loading the
mosaic package, try running the command
ds is a dataframe. This will open up an interactive visualizer that will output the code to generate the figure (using
ggformula) when you click on
