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.The packages argument may have up to 4 pieces of information for GitHub

getDeps(pkgDT, which, recursive, type = type, repos, libPaths, verbose)A (named) vector of SaveNames, which is a concatenation of the 2 or 4 elements
above, plus the which and the recursive.
A pkgDT object e.g., from toPkgDT
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".
Logical. Should dependencies of dependencies be searched,
recursively. NOTE: Dependencies of suggests will not be recursive. Default
TRUE.
is used for ap.
A path to search for installed packages. Defaults to
.libPaths()
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).
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)")
