spec_hist {kableExtra}

Helper functions to generate inline sparklines

Description

These functions helps you quickly generate sets of sparkline style plots using base R plotting system. Currently, we support histogram, boxplot, line, scatter and pointrange plots. You can use them together with column_spec to generate inline plot in tables. By default, this function will save images in a folder called "kableExtra" and return the address of the file.

Usage

spec_hist(
  x,
  width = 200,
  height = 50,
  res = 300,
  breaks = "Sturges",
  same_lim = TRUE,
  lim = NULL,
  xaxt = "n",
  yaxt = "n",
  ann = FALSE,
  col = "lightgray",
  border = NULL,
  dir = if (is_latex()) rmd_files_dir() else tempdir(),
  file = NULL,
  file_type = if (is_latex()) "pdf" else svglite::svglite,
  ...
)

Arguments

x

Vector of values or List of vectors of values.

width

The width of the plot in pixel

height

The height of the plot in pixel

res

The resolution of the plot. Default is 300.

breaks

The break option in hist. Default is "Sturges" but you can also provide a vector to manually specify break points.

same_lim

T/F. If x is a list of vectors, should all the plots be plotted in the same range? Default is True.

lim

Manually specify plotting range in the form of c(0, 10).

xaxt

On/Off for xaxis text

yaxt

On/Off for yaxis text

ann

On/Off for annotations (titles and axis titles)

col

Color for the fill of the histogram bar/boxplot box.

border

Color for the border.

dir

Directory of where the images will be saved.

file

File name. If not provided, a random name will be used

file_type

Graphic device. Can be character (e.g., "pdf") or a graphics device function (grDevices::pdf). This defaults to "pdf" if the rendering is in LaTeX and "svg" otherwise. for HTML output
