Choose an installed font from a list

Description

For a sequence of font family names, return the first one installed on the system. This makes it easy for code to specify a preferred font-family, but fall back to other font families if that is not installed on the system. This function acts much like the CSS font-family property.

Usage

choose_font(fonts, quiet = TRUE)

Arguments

Value

character. First font in fonts that is installed on the system or "" if none of those are installed.

Examples

choose_font(c("GillSans",  "Verdana", "sans"), quiet = TRUE)
choose_font(c("BemeboStd", "Garamond", "serif"), quiet = TRUE)
