get.function.dependencies2file: Determine all the dependencies of a function from a list of...

In drmjc/updateR: Package development toolkit

Description

If you've ever wanted to give someone a single function from within a package full of code, then you've probably forgotten a few other code functions & gone back & forth. Given a single function, this method will determine all the code dependencies. It only searches within a limited set of packages, such as those that you may have written yourself & not published yet. It will also tell you which CRAN/BioC packages need to be installed, but will ignore those packages which are automatically loaded at startup.

Usage

  get.function.dependencies2file(fun, file,
    packages = c(list.my.packages(src.root = getOption("src.root")), ".GlobalEnv"),
    src.files = NULL, verbose = FALSE)

Arguments

fun	either a function name, of the function's code
file	path to a file to write to
packages	vector of packages to search for dependencies in (ie packages that you probably wrote)
src.files	optional vector of R sources files to also search within. These have higher priority than code within packages.
verbose	logical: verbose output?

Value

nothing. writes a file containing source code.
