In this video, Mark Niemann-Ross demonstrates how to work with JSON in the R programming language. Learn how to import and export JSON data using the jsonlite package in R.
To import a JSON file,…use the read under bar JSON command.…It looks like this where I type in a vector…that I'm going to import it into…and I say read, under bar, J-S-O-N.…Notice that the dot and the under bar are important.…Then I'm going to specify a JSON file to import.…I have one in the sample files directory…and it's called J-S-O-N data dot J-S-O-N.…
Now if I just import it like this…I'll receive a list.…Instead, I want to receive a data frame…and to do that I type in simplifyVector…and I'll set that to true.…And when I hit command run this produces JSON import.…
