makeDepGraph | R Documentation |
Each package is a node, and a dependency is an edge
makeDepGraph( pkg, availPkgs, repos = getOption("repos"), type = "source", suggests = TRUE, enhances = FALSE, includeBasePkgs = FALSE, ... )
pkg |
Character vector of packages. |
availPkgs |
Data frame with an element called |
repos |
URL(s) of the 'contrib' sections of the repositories, e.g.
|
type |
Possible values are (currently) "source", "mac.binary" and
"win.binary": the binary types can be listed and downloaded but not
installed on other platforms. Passed to |
suggests |
If TRUE, retrieves Suggests dependencies (non-recursively) |
enhances |
If TRUE, retrieves Enhances dependencies (non-recursively) |
includeBasePkgs |
If TRUE, include base R packages in results |
... |
Other arguments passed to |
