DependsList object that
reports information about the packages the vignette depends on.
vignetteDepends(vignette, recursive = TRUE, reduce = TRUE, local = TRUE, lib.loc = NULL)"DependsList".
recursive is TRUE, any package that is specified as a
dependency will in turn have its dependencies included (and so on),
these are known as indirect dependencies. If recursive is
FALSE, only the dependencies directly named by the vignette
will be used. If local is TRUE, the system will only look at the
user's local machine and not online to find dependencies.
If reduce is TRUE, the system will collapse the fields in the
DependsList object such that a minimal set of dependencies
are specified (for instance if there was
foo, foo (>= 1.0.0), foo (>= 1.3.0, it would only return
foo (>= 1.3.0)).
