R: A simple JSON serializer

tojson {xfun} | R Documentation

## A simple JSON serializer

### Description

A JSON serializer that only works on a limited types of R data (`NULL`, lists, logical scalars, character/numeric vectors). A character string of the class `JS_EVAL` is treated as raw JavaScript, so will not be quoted. The function `json_vector()` converts an atomic R vector to JSON.

### Usage

    tojson(x)

    json_vector(x, to_array = FALSE, quote = TRUE)

### Arguments

`x` | An R object.
`to_array` | Whether to convert a vector to a JSON array (use `[]`).
`quote` | Whether to double quote the elements.

### Value

A character string.

### See Also

The jsonlite package provides a full JSON serializer.

### Examples

    library(xfun)
    tojson(NULL)
    tojson(1:10)
    tojson(TRUE)
    tojson(FALSE)
    cat(tojson(list(a = 1, b = list(c = 1:3, d = "abc"))))
    cat(tojson(list(c("a", "b"), 1:5, TRUE)))

    # the class JS_EVAL is originally from htmlwidgets::JS()
    JS = function(x) structure(x, class = "JS_EVAL")
    cat(tojson(list(a = 1:5, b = JS("function() {return true;}"))))
