A precise & pristine ggplot2 theme with opinionated defaults and an emphasis on typoghraphy

You should import_titillium_web first and also install the fonts on your system before trying to use this theme.

theme_ipsum_tw(base_family = "Titillium Web", base_size = 10.5,
  plot_title_family = if (.Platform$OS.type == "windows") "Titillium Web"
  else "Titillium Web Bold", plot_title_size = 18,
  plot_title_face = "bold", plot_title_margin = 10,
  subtitle_family = if (.Platform$OS.type == "windows") "Titillium Web"
  else "Titillium Web Light", subtitle_size = 13,
  subtitle_face = "plain", subtitle_margin = 15,
  strip_text_family = base_family, strip_text_size = 12,
  strip_text_face = "plain", caption_family = if (.Platform$OS.type ==
  "windows") "Titillium Web" else "Titillium Web Light",
  caption_size = 9, caption_face = "plain", caption_margin = 10,
  axis_text_size = base_size, axis_title_family = base_family,
  axis_title_size = 9, axis_title_face = "plain",
  axis_title_just = "rt", plot_margin = margin(30, 30, 30, 30),
  grid_col = "#cccccc", grid = TRUE, axis_col = "#cccccc",
  axis = FALSE, ticks = FALSE)

axis_title_just	axis title font justificationk one of [blmcrt]
plot_margin	plot margin (specify with ggplot2::margin)

Details

There is an option hrbrthemes.loadfonts which -- if set to TRUE -- will call extrafont::loadfonts() to register non-core fonts with R PDF & PostScript devices. If you are running under Windows, the package calls the same function to register non-core fonts with the Windows graphics device.

Why Titillium Web?

It's free, has tolerable kerning pairs and multiple weights. It's also different than Arial Narrow and the fonts most folks use in ggplot2 charts.
