Map over multiple inputs returning a link_fns_list

Analogous to purrr::pmap_dbl()

Usage

pmap_link_fns(.l, .f, ..., .progress = FALSE)

Arguments

.l

A list of vectors. The length of .l determines the number of arguments that .f will be called with. Arguments will be supply by position if unnamed, and by name if named.

Vectors of length 1 will be recycled to any length; all other elements must be have the same length.

A data frame is an important special case of .l. It will cause .f to be called once for each row.

.f

a function to apply to each .l item (usually an as.link_fns() call)

...

Additional arguments passed on to the mapped function.

We now generally recommend against using ... to pass additional (constant) arguments to .f. Instead use a shorthand anonymous function:

# Instead of
x |> map(f, 1, 2, collapse = ",")
# do:
x |> map(\(x) f(x, 1, 2, collapse = ","))

This makes it easier to understand which arguments belong to which function and will tend to yield better error messages.

.progress

Whether to show a progress bar. Use TRUE to turn on a basic progress bar, use a string to give it a name, or see progress_bars for more details.

Value

a link_fns_list
