JSON is just another format to ship data between programs / systems. Nothing really special. Just right now the most fashionable (some love to say “sexy”) data format. Some 10 years ago it was XML and some 10 years later we will certainly have something “even more sexy” then JSON…

Basically there are 3 different packages to handle JSON format in R:

  • rjson
  • jsonlite

All three have 2 command in common:

  • fromJSON
  • toJSON
