External image

Description

Wraps an image in an object that can then be embedded in a PowerPoint slide or within a Word paragraph.

The image is added as a shape in PowerPoint (it is not possible to mix text and images in a PowerPoint form). With a Word document, the image will be added inside a paragraph.

Usage

external_img(
  src,
  width = 0.5,
  height = 0.2,
  unit = "in",
  guess_size = FALSE,
  alt = ""
)

Arguments

src	image file path
width, height	size of the image file. It can be ignored if parameter guess_size=TRUE, see parameter guess_size.
unit	unit for width and height, one of "in", "cm", "mm".
guess_size	If package 'magick' is installed, this option can be used (set it to TRUE). The images will be read and width and height will be guessed.
alt	alternative text for images

usage

You can use this function in conjunction with fpar to create paragraphs consisting of differently formatted text parts. You can also use this function as an r chunk in an R Markdown document made with package officedown.
