spec_hist: 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
...: extra parameters sending to hist()
