Find srcrefs for namespace objects that wrap package functions

Wrappers such as Vectorize(f) or memoise::memoise(f) have no srcref of their own, but keep the function they wrap in their environment. Each namespace object without a srcref is searched this way, and given the srcrefs of the wrapped functions that belong to the same namespace. Code from other packages, such as helpers a wrapper uses internally, is left out.

Usage

wrapper_srcrefs(ns, exclude = character())

Arguments

ns

A package namespace environment

exclude

A character vector of object names that already have srcrefs

Value

A list of srcrefs, named by the wrapper they belong to
