plot_chunk: Mini plot chunk

In flextable: Functions for Tabular Reporting

Mini plot chunk

Description

This function is used to insert mini plots into flextable with functions:

• compose() and as_paragraph(),

• append_chunks(),

• prepend_chunks().

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

Usage

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

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".
alt	alternative text for the image (used for accessibility)
...	arguments sent to plot functions (see par())

Note

This chunk option requires package officedown in a R Markdown context with Word output format. With Quarto (format: docx) or rmarkdown::word_document(), the resulting file must be repaired with repair_docx().

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

  z = list(.SD$Sepal.Length)
), by = "Species"]

ft <- flextable(z,
  col_keys = c("Species", "Sepal.Length", "box", "density")
)
ft <- mk_par(ft, j = "box", value = as_paragraph(
  plot_chunk(
    value = z, type = "box",
    border = "red", col = "transparent"
  )
))
ft <- mk_par(ft, j = "density", value = as_paragraph(
  plot_chunk(value = z, type = "dens", col = "red")
))
ft <- set_table_properties(ft, layout = "autofit", width = .6)
ft <- set_header_labels(ft, box = "boxplot", density = "density")
