In vegalite: Tools to Encode Visualizations with the 'Grammar of Graphics'-Like 'Vega-Lite' 'Spec'

Description

Create and (optionally) visualize a Vega-Lite spec

Usage

vegalite(description = "", renderer = c("svg", "canvas"), export = FALSE,
  source = FALSE, editor = FALSE, viewport_width = NULL,
  viewport_height = NULL, background = NULL, time_format = NULL,
  number_format = NULL)

Arguments

description	a single element character vector that provides a description of the plot/spec.
renderer	the renderer to use for the view. One of canvas or svg (the default)
export	if TRUE the "Export as..." link will be displayed with the chart.(Default: FALSE.)
source	if TRUE the "View Source" link will be displayed with the chart. (Default: FALSE.)
editor	if TRUE the "Open in editor" link will be displayed with the cahrt. (Default: FALSE.)
viewport_width, viewport_height	height and width of the overall visualziation viewport. This is the overall area reserved for the plot. You can leave these NULL and use cell_size instead but you will want to configure both when making faceted plots.
background	plot background color. If NULL the background will be transparent.
time_format	the default time format pattern for text and labels of axes and legends (in the form of D3 time format pattern). Default: %Y-%m-%d
number_format	the default number format pattern for text and labels of axes and legends (in the form of D3 number format pattern). Default: s
