RJSONIO fromJSON error

Question

I have a problem with the fromJSON function in RJSONIO package in R.

I have a json file to read with fromJSON

{"indy movies" :[
{
"name" : "Raiders of the Lost Ark",
"year" : 1981,
"actors" : {
    "Indiana Jones": "Harrison Ford", 
    "Dr. René Belloq": "Paul Freeman" 
    },
"producers": ["Frank Marshall", "George Lucas", "Howard Kazanjian"],
"budget" : 18000000,
"academy_award_ve": true
},
{
"name" : "Indiana Jones and the Temple of Doom",
"year" : 1984,
"actors" : {
    "Indiana Jones": "Harrison Ford", 
    "Mola Ram": "Amish Puri"
    },
"producers": ["Robert Watts"],
"budget" : 28170000,
"academy_award_ve": true
},
{
"name" : "Indiana Jones and the Last Crusade",
"year" : 1989,
"actors" : {
    "Indiana Jones": "Harrison Ford", 
    "Walter Donovan": "Julian Glover"
    },
"producers": ["Robert Watts", "George Lucas"],
"budget" : 48000000,
"academy_award_ve": false
}]}

The file name is "indy.json"

Here is a reproducible example:

indy <- fromJSON(content = "indy.json")

However,i get the result:

> indy <- fromJSON(content = "indy.json")
Error in nchar(content) : invalid multibyte string, element 1

Here is my relevant sessionInfo()

R version 3.3.3 (2017-03-06)
Platform: x86_64-apple-darwin13.4.0 (64-bit)
Running under: macOS Sierra 10.12.4

Can anyone please suggest why this is happening?

I also use Mac, W.david, and your code ran fine for me. Have you opened up your JSON file in a text editor like Atom or Sublime Text to check if there are NULLs or something like that? These multibyte errors usually come from some type of unusual character in the file, like ` ñ `, etc. — RobertMyles, Oct 06 '17 at 17:14

Try using the jsonlite package instead. I pasted your string in a file, saved it as t.R, then read it back in. The string is represented as yours above.
