This function is used to insert mini plots into flextable with function compose(). It should be used inside a call to as_paragraph().

Available plots are 'box', 'line', 'points', 'density'.

plot_chunk(
  value,
  width = 1,
  height = 0.2,
  type = "box",
  free_scale = FALSE,
  unit = "in",
  ...
)

Arguments

value

a numeric vector, stored in a list column.

width, height

size of the resulting png file in inches

type

type of the plot: 'box', 'line', 'points' or 'density'.

free_scale

Should scales be free (TRUE or FALSE, the default value).

unit

unit for width and height, one of "in", "cm", "mm".

...

arguments sent to plot functions (see par())

Note

This chunk option requires package officedown in a R Markdown context with Word output format.

PowerPoint cannot mix images and text in a paragraph, images are removed when outputing to PowerPoint format.
