Preface

Formatting

The following ggplot2 theme was used to format all plots in this book:

plot_style <- function() {
  font <- "Helvetica"

  ggplot2::theme_classic() +
  ggplot2::theme(
    plot.title = ggplot2::element_text(
      family = font, size=14, color = "#222222"),
    plot.subtitle = ggplot2::element_text(
      family=font, size=12, color = "#666666"),

    legend.position = "right",
    legend.background = ggplot2::element_blank(),
    legend.title = ggplot2::element_blank(),
    legend.key = ggplot2::element_blank(),
    legend.text = ggplot2::element_text(
      family=font, size=14, color="#222222"),

    axis.title.y = ggplot2::element_text(
      margin = ggplot2::margin(t = 0, r = 8, b = 0, l = 0),
      size = 14, color="#666666"),
    axis.title.x = ggplot2::element_text(
      margin = ggplot2::margin(t = -2, r = 0, b = 0, l = 0),
      size = 14, color = "#666666"),
    axis.text = ggplot2::element_text(
      family=font, size=14, color="#222222"),
    axis.text.x = ggplot2::element_text(
      margin = ggplot2::margin(5, b = 10)),
    axis.ticks = ggplot2::element_blank(),
    axis.line = ggplot2::element_blank(),

    panel.grid.minor = ggplot2::element_blank(),
    panel.grid.major.y = ggplot2::element_line(color = "#eeeeee"),
    panel.grid.major.x = ggplot2::element_line(color = "#ebebeb"),

    panel.background = ggplot2::element_blank(),

    strip.background = ggplot2::element_rect ...
