spec_pointrange: 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_pointrange(
  x,
  xmin,
  xmax,
  vline = NULL,
  width = 200,
  height = 50,
  res = 300,
  same_lim = TRUE,
  lim = NULL,
  xaxt = "n",
  yaxt = "n",
  ann = FALSE,
  col = "red",
  line_col = "black",
  cex = 0.3,
  frame.plot = FALSE,
  dir = if (is_latex()) rmd_files_dir() else tempdir(),
  file = NULL,
  file_type = if (is_latex()) "pdf" else svglite::svglite,
  ...
)

Arguments

x, xmin, xmax: A scalar value or List of scalar values for dot, left and right error bar.
vline: A scalar value for where to draw a vertical line.
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.
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 mean dot.
line_col: Color for the line and the error bar.
cex: size of the mean dot and error bar size.
frame.plot: T/F for whether to plot the plot frames.
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()
