Find an available font family for a poster — poster

Chooses a font family that is actually installed on the system, so that output renders (and embeds into PDF) without falling back to a substitute. Latin text prefers clean sans-serif faces; CJK text prefers a Japanese capable family.

Usage

poster_font(cjk = FALSE, preferred = NULL, fallback = "")

Arguments

cjk: If TRUE, look for a CJK (Japanese) capable family.
preferred: Character vector of family names to try, in order. If NULL, a built-in list of common families is used.
fallback: Family name to return when none of preferred is installed. Defaults to the empty string, which lets the graphics device pick.

Value

A single font family name (character scalar).

Examples

poster_font()
#> [1] "DejaVu Sans"
poster_font(cjk = TRUE)
#> [1] ""
