Jeroen: Thank you for pointing me to ndjson, which I had not heard of and is exactly my case. My experience: jsonlite::stream_in - segfaults ndjson::stream_in - my fault, I am running Ubuntu 14.04 and it is too old so it won't compile the package corpus::read_ndjson - works!!! Of course it does a different simplification than jsonlite::fromJSON, so I have to change some code, but it works beaut...

Hi: I have a 2.1GB JSON file. Typically I use readLines() and jsonlite:fromJSON() to extract data from a JSON file. When I try and read in this file using readLines() R segfaults. I believe the two salient issues with this file are 1). Its size 2). It is a single line (no line breaks) I can reproduce this issue as follows #Generate a big file with no line breaks #...

Recent functionality in jsonlite allows for streaming json to a user supplied connection object, such as a file, pipe or socket. RFC7159 prescribes json must be encoded as unicode; ISO-8859 (including latin1) is invalid. Hence I would like R to write strings as utf8, irrespective of the type of connection, platform or locale. Impl...

Hi, Both vapply() and sapply() support the 'USE.NAMES' argument. According to the man page: USE.NAMES: logical; if ?TRUE? and if ?X? is character, use ?X? as ?names? for the result unless it had names already. But if 'X' has names already and 'USE.NAMES' is FALSE, it's not clear what will happen to the names. Are they going to propagate to the result

...cesses using a simple socket mechanism. The messages are rather long object stored as JSON. R is crashing with a segmentation fault when I try to read my test message (which is 5305 bytes long).
