[Deprecated]

funs() is deprecated; please use list() instead. We deprecated this function because it provided a unique way of specifying anonymous functions, rather than adopting the conventions used by purrr and other packages in the tidyverse.

funs(..., .args = list())

Arguments

...

<data-masking> A list of functions specified by:

  • Their name, "mean"

  • The function itself, mean

  • A call to the function with . as a dummy argument, mean(., na.rm = TRUE)

The following notations are not supported, see examples:

  • An anonymous function, function(x) mean(x, na.rm = TRUE)

  • An anonymous function in purrr notation, ~mean(., na.rm = TRUE)

.args, args

A named list of additional arguments to be added to all function calls. As funs() is being deprecated, use other methods to supply arguments: ... argument in scoped verbs or make own functions with purrr::partial().

Examples
