Map at depth

This function is defunct and has been replaced by map_depth(). See also modify_depth() for a version that preserves the types of the elements of the tree.

at_depth(.x, .depth, .f, ...)

Arguments

.x	A list or atomic vector.
.depth	Level of .x to map on. Use a negative value to count up from the lowest level of the list. map_depth(x, 0, fun) is equivalent to fun(x). map_depth(x, 1, fun) is equivalent to x <- map(x, fun) map_depth(x, 2, fun) is equivalent to x <- map(x, ~ map(., fun))
.f	A function, formula, or vector (not necessarily atomic). If a function, it is used as is. If a formula, e.g. ~ .x + 2, it is converted to a function. There are three ways to refer to the arguments: For a single argument function, use . For a two argument function, use .x and .y For more arguments, use ..1, ..2, ..3 etc This syntax allows you to create very compact anonymous functions. If character vector, numeric vector, or list, it is converted to an extractor function. Character vectors index by name and numeric vectors index by position; use a list to index by position and name at different levels. If a component is not present, the value of .default will be returned.
...	Additional arguments passed on to the mapped function.
