read_json function

Read/write JSON

These functions are similar to toJSON() and fromJSON() except they explicitly distinguish between path and literal input, and do not simplify by default.

read_json(path, simplifyVector = FALSE, ...)

parse_json(json, simplifyVector = FALSE, ...)

write_json(x, path, ...)

Arguments

• path: file on disk
• simplifyVector: simplifies nested lists into vectors and data frames. See fromJSON().
• ...: additional conversion arguments, see also toJSON() or fromJSON()
• json: string with literal json or connection object to read from
• x: an object to be serialized to JSON

Examples

tmp <- tempfile()
write_json(iris, tmp)

# Nested lists
read_json(tmp)

# A data frame
read_json(tmp, simplifyVector = TRUE)
