#' 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.
|
|
#'
|
|
#' 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.

|
|
#' 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.
