Description

This class represents the code chunks and other related information from a vignette file. It also provides for the ability to evaulate the code chunks in a separate environment.

Objects from the Class

Objects can be created by calls of the form new("vignetteCode", ...) Also, a helper function getVignetteCode is provided that will do all of the dirty work required to retrieve a vignetteCode object from a vignette file.

Slots

chunkList:

Object of class "chunkList" Holds the code chunks from the vignette file

path:

Object of class "character" The path of the vignette file

vigPackage:

Object of class "character" The package (if appropriate) that the vignette came from

depends:

Object of class "character" Any package dependencies for the vignette

evalEnv:

Object of class "environment" An environment used for evaluation of the code chunks.

Methods

show

signature(object = "vignetteCode"): Displays information about the code contained in the object

chunkList

signature(object = "vignetteCode"): Retrieves the chunkList object.

chunks

signature(object = "vignetteCode"): Retrieves the actual code chunks (not wrapped by the chunkList class)

getDepends

signature(object = "vignetteCode"): Returns the list of package dependencies for this vignette

evalChunk

signature(object = "vignetteCode",pos="numeric"): Will evaulate the specified code chunk in the evalEnv environment

evalEnv

signature(object = "vignetteCode"): Returns the evaluation environment

getChunk

signature(object = "vignetteCode",pos="numeric"): Returns the codeChunk object representing the specified code chunk position

numChunks

signature(object = "vignetteCode"): Returns the number of chunks in the object

vigPackage

signature(object = "vignetteCode"): Returns the package the vignette is a part of

path

signature(object = "vignetteCode"): Returns the local file path to the vignette

setChunk<-

signature(object = "vignetteCode",pos="numeric", value="character"): Resets the code chunk specified by pos to contain the code specified by value

summary

signature(object = "vignetteCode"): A less verbose output of information then with show
