string_width {systemfonts} | R Documentation

## Calculate the width of a string, ignoring new-lines

### Description

This is a very simple alternative to `shape_string()` that simply calculates the width of strings without taking any newline into account. As such it is suitable to calculate the width of words or lines that has already been splitted by `\n`. Input is recycled to the length of `strings`.

### Usage

    string_width(
      strings,
      family = "",
      italic = FALSE,
      bold = FALSE,
      size = 12,
      res = 72,
      include_bearing = TRUE,
      path = NULL,
      index = 0
    )

### Arguments

`strings` | A character vector of strings
`family` | The name of the font family
`italic` | logicals indicating the font style
`bold` | logicals indicating the font style
`size` | The pointsize of the font to use for size related measures
`res` | The ppi of the size related mesures
`include_bearing` | Logical, should left and right bearing be included in the string width?
`path` | path an index of a font file to circumvent lookup based on family and style
`index` | path an index of a font file to circumvent lookup based on family and style

### Value

A numeric vector giving the width of the strings in pixels. Use the provided `res` value to convert it into absolute values.

### Examples

    strings <- c('A short string', 'A very very looong string')
    string_width(strings)
