Parse JSON with R -


i new r, more use it, more see how powerful on sas or spss. 1 of major benefits, see them, ability , analyze data web. imagine possible (and maybe straightforward), looking parse json data publicly available on web. not programmer stretch, , instruction can provide appreciated. if point me basic working example, can work through it.

rjsonio omegahat package provides facilities reading , writing data in json format.

rjson not use s4/s3 methods , not readily extensible, still useful. unfortunately, not used vectorized operations , slow non-trivial data. similarly, reading json data r, slow , not scale large data, should issue.

update (new package 2013-12-03):

jsonlite: package fork of rjsonio package. builds on parser rjsonio, implements different mapping between r objects , json strings. c code in package rjsonio package, r code has been rewritten scratch. in addition drop-in replacements fromjson , tojson, package has functions serialize objects. furthermore, package contains lot of unit tests make sure edge cases encoded , decoded consistently use dynamic data in systems , applications.
