getArgFromCall: Accessor Functions

In duncantl/CodeAnalysis: Tools for Static Analysis of R code

Accessor Functions

Description

These are higher-level accessor functions for working with language objects and meta-programming so that we can talk about high-level operations and concepts and not the specific representation of R language objects.

Usage

getArgFromCall(call, arg, asCharacter = TRUE)
isFunAssign(x, toSymbol = TRUE) 
pkgSymbolsUsed(pkg, fromPkg, ns = getNamespace(pkg), exportedOnly = TRUE) 

Arguments

call, x	the R call language object
arg	the name of the argument to extract from the call
asCharacter	a logical value controlling whether to deparse the result or leave it is a language object
pkg	the name of the package which is calling functions from another package
fromPkg	the name of the other package whose functions are being called
ns	the namespace's environment
exportedOnly	a logical value. If TRUE, only the exported symbols are considered, otherwise all the symbols in the namespace are processed.
toSymbol	a logical value that if TRUE causes isFunAssign not look at the value of the symbol to which the value is being assigned.

Value

a character vector/string or a language object.
