There was a problem encountered while trying to import Json data

I'm having trouble importing my JSON file into R. I've installed the necessary packages and here's what I attempted:

library(rjson)
JsonData <- fromJson(file= "<filename.json>")

I also tried using the file path and the jsonlite package, but encountered this error message:

Error in file(con, "r"): can not open the connection. In addition: Warning message: cannot open file '': invalid argument

Despite ensuring everything is set up correctly, I am unable to get it to work. I've explored other available options as well!

Answer №1

Transform data into JSON format from a specific file by using the command <code>JsonData <- fromJSON(file= "filename.json")

It is important to remember that in R, capitalization matters so ensure you change fromJson to fromJSON. Additionally, remove the greater-than and less-than symbols (< and >) from the file path for accurate execution.
