Explain dependencies of a package treeSource:
These functions are similar to
pkg_deps_explain(), but work on a
local package tree.
local_dev_deps_explain() also includes development
local_deps_explain(deps, root = ".", upgrade = TRUE, dependencies = NA) local_dev_deps_explain(deps, root = ".", upgrade = TRUE, dependencies = TRUE)
Package names of the dependencies to explain.
Path to the package tree.
Whether to use the most recent available package versions.
What kinds of dependencies to install. Most commonly one of the following values:
NA: only required (hard) dependencies,
TRUE: required dependencies plus optional and development dependencies,
FALSE: do not install any dependencies. (You might end up with a non-working package, and/or the installation might fail.) See Package dependency types for other possible values and more information about package dependencies.
