Font size specification

Font size specification

font_spec(font_family = "Courier", font_size = 8, lineheight = 1)

Arguments

font_family

(character(1))
font family to use during string width and lines-per-page calculations. You can specify "Times New Roman" as "Times" or "serif", regardless of OS. Beyond that, see family entry in graphics::par() for details.

font_size

(numeric(1))
font size to use during string width calculations and lines-per-page calculations.

lineheight

(numeric(1))
line height to use during lines-per-page calculations.

Details

Passing the output of this constructor to the rendering or pagination machinery defines a font for use when calculating word wrapping and pagination.

Note

Specifying font in this way to, e.g., export_as_txt() or toString() will not affect the font size of the output, as these are both raw text formats. export_as_pdf() will use the specified font.

Examples

fspec <- font_spec("Courier", 8, 1)

lets <- paste(letters, collapse = "")

nchar_ttype(lets, fspec)
#> [1] 26

fspec2 <- font_spec("Times", 8, 1)

nchar_ttype(lets, fspec2)
#> [1] 48
