dots_values
From rlang v0.1.6
by Lionel Henry
Evaluate dots with preliminary splicing
This is a tool for advanced users. It captures dots, processes
unquoting and splicing operators, and evaluates them. Unlike
dots_list() and dots_splice(), it does not flatten spliced
objects. They are merely attributed a spliced class (see
splice()). You can process spliced objects manually, perhaps with
a custom predicate (see flatten_if()).
Usage
dots_values(..., .ignore_empty = c("trailing", "none", "all"))Arguments
- ...
Arguments to evaluate and process splicing operators.
- .ignore_empty
Whether to ignore empty arguments. Can be one of
"trailing","none","all". If"trailing", only the last argument is ignored if it is empty.
Examples
# NOT RUN {
dots <- dots_values(!!! list(1))
dots
# Flatten the spliced objects:
flatten_if(dots, is_spliced)
# }
