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_plot(
  x,
  y = NULL,
  width = 200,
  height = 50,
  res = 300,
  same_lim = TRUE,
  xlim = NULL,
  ylim = NULL,
  xaxt = "n",
  yaxt = "n",
  ann = FALSE,
  col = "lightgray",
  border = NULL,
  frame.plot = FALSE,
  lwd = 2,
  pch = ".",
  cex = 2,
  type = "l",
  polymin = NA,
  minmax = list(pch = ".", cex = cex, col = "red"),
  min = minmax,
  max = minmax,
  dir = if (is_latex()) rmd_files_dir() else tempdir(),
  file = NULL,
  file_type = if (is_latex()) "pdf" else svglite::svglite,
  ...
)

Arguments

x, y	Vector of values or List of vectors of values. y is optional.
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.
same_lim	T/F. If x is a list of vectors, should all the plots be plotted in the same range? Default is True.
xlim, ylim	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.
frame.plot	On/Off for surrounding box (spec_plot only). Default is False.
lwd	Line width for spec_plot; within spec_plot, the minmax argument defaults to use this value for cex for points. Default is 2.
pch, cex	Shape and size for points (if type is other than "l").
type	Passed to plot, often one of "l", "p", or "b", see graphics::plot.default() for more details. Ignored when polymin is not NA.
polymin	Special argument that converts a "line" to a polygon, where the flat portion is this value, and the other side of the polygon is the 'y' value ('x' if no 'y' provided). If NA (the default), then this is ignored; otherwise if this is numeric then a polygon is created (and 'type' is ignored). Note that if polymin is in the middle of the 'y' values, it will generate up/down polygons around this value.
minmax, min, max	Arguments passed to points to highlight minimum and maximum values in spec_plot. If min or max are NULL, they default to the value of minmax. Set to an empty list() to disable.
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.
...	extra parameters passing to plot
