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

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

theme_ocha(base_family = "Roboto Condensed", base_size = 11.5,
  plot_title_family = base_family, plot_title_size = 18,
  plot_title_face = "bold", plot_title_margin = 10,
  subtitle_family = if (.Platform$OS.type == "windows")
  "Roboto Condensed" else "Roboto Condensed Light", subtitle_size = 13,
  subtitle_face = "plain", subtitle_margin = 15,
  strip_text_family = base_family, strip_text_size = 12,
  strip_text_face = "plain", caption_family = if (.Platform$OS.type ==
  "windows") "Roboto Condensed" else "Roboto Condensed 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_family, axis_title_face, axis_title_size	axis title font family, face and size
axis_title_just	axis title font justificationk one of [blmcrt]
plot_margin	plot margin (specify with ggplot2::margin)
grid_col	grid color
grid	panel grid (TRUE, FALSE, or a combination of X, x, Y, y)

Details

There is an option ochathemes.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 Roboto Condensed?

It's free, has tolerable kerning pairs and multiple weights.
