    class file, like file('c:/temp/cars.txt','rb')
    class json, like ec.inspect(p), for options or full
    class character, JSON string with options only, see example below

Details

txt could be either a list of options (x$opts) to be set by setOption,
OR an entire htmlwidget generated thru ec.inspect with target='full'.
The latter imports all JavaScript functions defined by the user.

Examples

txt <- '{
   "xAxis": { "data": ["Mon", "Tue", "Wed"]}, "yAxis": { },
   "series": { "type": "line", "data": [150, 230, 224] } }'
ec.fromJson(txt)  # text json

# outFile <- 'c:/temp/cars.json'
# cars |> ec.init() |> ec.inspect(target='full', file=outFile)
# ec.fromJson(file(outFile, 'rb'))
# ec.fromJson(url('http://localhost/echarty/cars.json'))
