Draw alternative lollipop and density plots with ggalt

This is another creation from the R master sorcerer, Bob Rudis. This package called ggalt displays lots of alternative geometries and statistical transformations addressed to ggplot2. For example, we could name stat_bkde() and stat_bkde2d(), which use alternative functions to create kernel density estimates (respectively for one and two dimensions).

This recipe demonstrates how to use ggalt to craft these two kinds of visuals with the help of the car::Salaries package. The recipe also demonstrates how to easily craft lollipop plots using geom_lollipop(). This last example uses the car::Migration dataset.

Getting Ready

Both car and ggalt packages can be obtained from CRAN:

if(!require(ggalt)){install.packages('ggalt')}
if(!require(car)){install.packages('car')}

With both packages installed we can go on.

How to do it...

While density estimates are drawn using the Salaries data frame, the lollipop plot uses Migration, both coming from the car...
