Manage 'dependencies' argument

[Enchufa2]

From help(install.packages):

dependencies: logical indicating whether to also install uninstalled
          packages which these packages depend on/link
          to/import/suggest (and so on recursively).  Not used if
          ‘repos = NULL’.  Can also be a character vector, a subset of
          ‘c("Depends", "Imports", "LinkingTo", "Suggests",
          "Enhances")’.

          Only supported if ‘lib’ is of length one (or missing), so it
          is unambiguous where to install the dependent packages.  If
          this is not the case it is ignored, with a warning.

          The default, ‘NA’, means ‘c("Depends", "Imports",
          "LinkingTo")’.

          ‘TRUE’ means to use ‘c("Depends", "Imports", "LinkingTo",
          "Suggests")’ for ‘pkgs’ and ‘c("Depends", "Imports",
          "LinkingTo")’ for added dependencies: this installs all the
          packages needed to run ‘pkgs’, their examples, tests and
          vignettes (if the package author specified them correctly).

          In all of these, ‘"LinkingTo"’ is omitted for binary
          packages.
