getDeps {Require}

The packages argument may have up to 4 pieces of information for GitHub packages: name, repository, branch, version. For CRAN-alikes, it will only be 2 pieces: name, version. There can also be an inequality or equality, if there is a version.

Description

The packages argument may have up to 4 pieces of information for GitHub packages: name, repository, branch, version. For CRAN-alikes, it will only be 2 pieces: name, version. There can also be an inequality or equality, if there is a version.

Usage

getDeps(pkgDT, which, recursive, type = type, repos, libPaths, verbose)

Arguments

pkgDT

A pkgDT object e.g., from toPkgDT

which

a character vector listing the types of dependencies, a subset of c("Depends", "Imports", "LinkingTo", "Suggests", "Enhances"). Character string "all" is shorthand for that vector, character string "most" for the same vector without "Enhances".

recursive

Logical. Should dependencies of dependencies be searched, recursively. NOTE: Dependencies of suggests will not be recursive. Default TRUE.

type

See utils::install.packages

repos

is used for ap.

libPaths

A path to search for installed packages. Defaults to .libPaths()

verbose

Numeric or logical indicating how verbose should the function be. If -1 or -2, then as little verbosity as possible. If 0 or FALSE, then minimal outputs; if 1 or TRUE, more outputs; 2 even more. NOTE: in Require function, when verbose >= 2, also returns details as if returnDetails = TRUE (for backwards compatibility).

Details

If version is not supplied, it will take the local, installed version, if it exists. Otherwise, it is assumed that the HEAD is desired. The function will find it in the ap or on github.com. For github packages, this is obviously a slow step, which can be accelerated if user supplies a sha or a version e.g., getDeps("PredictiveEcology/LandR@development (==1.0.2)")

Value

A (named) vector of SaveNames, which is a concatenation of the 2 or 4 elements above, plus the which and the recursive.
