gf_bar()

The gf_bar() function creates a bar graph. It can be used to visualize the distribution of a categorical variable by counting the number of observations for each group of the category.

Bar graphs can also be used with the gf_facet_grid() function.

Example 1:

gf_bar( ~ Sex , data = Fingers )

Example of output from running the code above:

Example 2:

gf_bar( ~ RaceEthnic, data = Fingers) %>%

    gf_facet_grid(Sex ~ .)

​

Example of output from running the code above:

  The gf_lm() function overlays the best-fitting regression line on a scatter plot when chained onto gf_point(). Example: # adds a regression line gf_point(Thumb ~ Height, data = Fingers) %>%       gf_lm( color = "orange", size = 2 )

• gf_density()

  The gf_density() function will overlay a density plot onto a density histogram (i.e., gf_dhistogram(), not gf_histogram()). The density plot is a smoothed out version of the distribution. They can be helpful when you want to get a better idea of the ...
