sel_plot: Create a dynamic image object containing plots

In bschneidr/r_html_select: Add Interactive Functionality in HTML Documents Using Only Client-side HTML and JavaScript

Description

Create a dynamic image object containing plots

Usage

sel_plot(sel_id = "ts_1", options = NULL, fig_output_dir = NULL,
  dev = "png", fig.width = NULL, fig.height = NULL, dpi = NULL,
  embed = TRUE)

Arguments

sel_id	The id of the selector used to choose options
options	A named list of plot objects, with the number of options and names of options matching those used in the selector object.
fig_output_dir	Filepath of the directory where plots should be saved. If unspecified, the default output directory for the current knitr chunk will be used.
dev	The device to be used for saving the plots ('png', 'jpg', 'pdf', etc.)
fig.width	Plot width in inches. This can be a single number or a numeric vector matching the number of options.
fig.height	Plot length in inches. This can be a single number or a numeric vector matching the number of options.
dpi	The resolution of the image.
embed	A logical vector for whether images should be embedded directly into the HTML code as base64 strings. If FALSE, image files are referred to via links in the HTML code.

Value

Raw HTML representing the image object. If 'embed = FALSE', image files are created and saved in a directory determined by 'fig_output_dir'.
