Usage

ppl(.key, ...)

ppls(.keys, ...)

.key	⁠[character(1)]⁠ The key of the Graph in mlr_graphs.
...	any Additional parameters to give to constructed object. This may be an argument of the constructor of the underlying function.
.keys	⁠[character]⁠ The key of possibly multiple Graphs in mlr_graphs. If this is named, a named list is returned, but unlike pos() it will not set any ⁠$id⁠ slots.
