R: Serialize R objects as Javsscript/ActionScript variables

asJSVars

R Documentation

Serialize R objects as Javsscript/ActionScript variables

Description

This function takes R objects and serializes them as Javascript/ActionScript values. It uses the specified names in the R call as Javascript variable names. One can also specify qualifiers (‘public’, ‘protected’, ‘private’) and also types. These are optional, but useful, in ActionScript.

Usage

asJSVars(..., .vars = list(...), qualifier = character(), types = character())

Arguments

`...`	`name = value` pairs where the `value` is an R object that is converted to JSON format and `name` is the name of the corresponding Javascript variable.
`.vars`	this is an alternative to ... as a way to specify a collection of `name = value` pairs that is already in a list.
`qualifier`	a character vector (recycled as necessary) which is used as qualifiers for the individual ActionScript variables. The values should be public, protected or private.
`types`	either a logical value or a character vector (which is recycled if necessary). If this is `TRUE`, then we compute the Javascript type for each of the R objects (using the non-exported function `jsType`)

Value

A character vector of length 1 giving the variable declarations and initializations.

Examples

 cat(asJSVars( a =  1:10, myMatrix = matrix(1:15, 3, 5)))
 cat(asJSVars( a =  1:10, myMatrix = matrix(1:15, 3, 5), types = TRUE))
 cat(asJSVars( a =  1:10, myMatrix = matrix(1:15, 3, 5),
        qualifier = "protected", types = TRUE))
