Formula interface to ggplot2

ggformula introduces a family of graphics functions, gf_point(), gf_density(), and so on, bring the formula interface to ggplot(). This captures and extends the excellent simplicity of the lattice-graphics formula interface, while providing the intuitive “add this component” capabilities of ggplot2.

Installation

You can install ggformula from github with:

# install.packages("devtools")
devtools::install_github("ProjectMOSAIC/ggformula")

Using ggformula

The following example illustrates a typical plot constructed with ggformula.

suppressPackageStartupMessages(library(ggformula))
gf_jitter(Sepal.Length ~ Sepal.Width, data = iris, color = ~ Species,
          width = 0.05, height = 0.05, alpha = 0.6) %>%
  gf_density2d(alpha = 0.3) %>%
  gf_labs(title = "A famous data set",
          caption = "Data available in datasets package",
          ylab = "sepal length",
          xlab = "sepal width"
  ) %>%
  gf_theme(theme_bw()) %>%
  gf_theme(text = element_text(colour = "navy", face = "italic"))
