Basic Graphs for Variables in Datasets

Most of the graphs for datasets use the formula interface and are part of the lattice package, which is loaded together with the hanoverbase package.

• We will be using the ggformula package, which works well the ggplot package while providing a basic formula interface to the different graphs.
• It is hard to produce pie and pareto charts this way. You can look at the basic cheatsheet for ways to produce those kinds of charts.
• ggformula commands expect the dataset as their first argument, and therefore can work well with the pipe operator %>%

Use vignette("ggformula") within RStudio or this link to see more examples of ggformula.

library(hanoverbase)
library(ggformula)
data(brfss)

gf_counts(brfss, ~genhealth)
brfss %>% gf_bar(~genhealth)
brfss %>% gf_barh(~genhealth)
brfss %>% gf_countsh(~genhealth, fill="blue", col="black")
brfss %>% gf_countsh(~genhealth, geom="point")
brfss %>% gf_percentsh(~genhealth)
brfss %>% gf_percents(~genhealth)

library(hanoverbase)
library(ggformula)
data(counties)

counties %>% gf_histogram(~female)
counties %>% gf_boxplot(~female)
counties %>% gf_boxploth(1~female)
