json_tree_view: JSON tree viewer

In hrbrmstr/jsonview: View, Format, and "Pretty Print" 'JSON' Content

Description

Pass in a plaintext JSON or an R list to see formatted JSON in a viewer.

Usage

json_tree_view(x, auto_unbox = TRUE, scroll = FALSE, elementId = NULL,
  width = "100%", height = NULL)

Arguments

x	plaintext JSON or an R list
auto_unbox	passed to fromJSON (more on this when I have time for documentation)
scroll	should the <div> holding the HTML/XML content scroll (TRUE) or take up the full viewer/browser window (FALSE). Default is FALSE (take up the full viewer/browser window). If this is set to TRUE, height should be set to a value other than NULL.
elementId	element id
width	widget width (best to keep it at 100%)
height	widget height (kinda only useful for knitting since this is meant to be an interactive tool).

Details

It uses the jsonlite package to deal with gnarly lists (h/t @jennybryan).

Examples

library(jsonlite)

# available styles
highlight_styles()

# plain character

"glossary": {
"title": "example glossary",
"GlossDiv": {
