[R] Reading Json data

[Mayukh Dass]

Hello,

I am trying to read a set of json files containing tweets using the
following code:

json_data <- fromJSON(paste(readLines(json_file))

Unfortunately, it only reads the first record on the file. For example, in
the file below, it only reads the first record starting with "id":"tag:
search.twitter.com,2005:3318539389". What is the best way to retrieve these
records? I have 20 such json files with varying number of tweets in it.
Thank you in advance.

Best,
Mayukh
