| vignetteDepends {tools} | R Documentation |
Given a vignette name, will create a DependsList object that reports information about the packages the vignette depends on.
vignetteDepends(vignette, recursive = TRUE, reduce = TRUE,
local = TRUE, lib.loc = NULL)
vignette |
The path to the vignette source |
recursive |
Whether or not to include indirect dependencies |
reduce |
Whether or not to collapse all sets of dependencies to a minimal value |
local |
Whether or not to search only locally |
lib.loc |
What libraries to search in locally |
If 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 to the minimal set of dependencies (for
instance if the dependencies were ('foo', 'foo (>= 1.0.0)',
'foo (>= 1.3.0)'), the return value would be 'foo (>= 1.3.0)').
