jsonedit

View Lists with 'jsoneditor'

Description

jsonedit provides a flexible and helpful interactive tree-like view of lists or really any R dataset that can be represented as JSON. Eventually, this could become a very nice way to not only view but also modify R data using Shiny.

Usage

jsonedit(listdata = NULL, mode = "tree", modes = c("code", "form",
  "text", "tree", "view"), ..., width = NULL, height = NULL,
  elementId = NULL)

Arguments

`listdata`	`list` or `String` data to view. Although designed for `lists`, `listdata` can be any data source that can be rendered into `JSON` with `jsonlite`. Alternately, `listdata` could be a `String` of valid `JSON`. This might be helpful when dealing with an API response.
`mode`	`string` for the initial view from `modes`. `'tree'` is the default.
`modes`	`string` `c('code', 'form', 'text', 'tree', 'view')` will be the default, since these are all the modes currently supported by `jsoneditor`.
`...`	`list` of other options for `jsoneditor`. This is a temporary way of trying other options in `jsoneditor`. In the future, this will be eliminated in favor of specific, more self-documenting and helpful arguments.
`width`	integer in pixels defining the width of the `div` container.
`height`	integer in pixels defining the height of the `div` container.
`elementId`	character to specify valid `CSS` id of the htmlwidget for special situations in which you want a non-random identifier.

Examples

library(listviewer)

   # using the data from the jsoneditor simple example
   #  in R list form
   jsonedit(
     list(
       array = c(1,2,3)
       ,boolean = TRUE
       ,null = NULL
       ,number = 123
       ,object = list( a="b", c="d" )
       ,string = "Hello World"
     )
   )

   # jsonedit also works with a JSON string
   jsonedit(
     '{"array" : [1,2,3] , "boolean" : true, "null" : null, number = 123}'
   )

   # also works with most data.frames
   jsonedit( mtcars )

   # helpful interactive view of par
   jsonedit( par() )
