vec_unchop: Chopping

In vctrs: Vector Helpers

Chopping

Description

vec_unchop() has been renamed to list_unchop() and is deprecated as of vctrs 0.5.0.

Usage

vec_unchop(
  x,
  indices = NULL,
  ptype = NULL,
  name_spec = NULL,
  name_repair = c("minimal", "unique", "check_unique", "universal")
)

Arguments

x	A list
indices	A list of positive integer vectors specifying the locations to place elements of x in. Each element of x is recycled to the size of the corresponding index vector. The size of indices must match the size of x. If NULL, x is combined in the order it is provided in, which is equivalent to using vec_c().
ptype	If NULL, the default, the output type is determined by computing the common type across all elements of x. Alternatively, you can supply ptype to give the output a known type.
name_spec	A name specification for combining inner and outer names. This is relevant for inputs passed with a name, when these inputs are themselves named, like outer = c(inner = 1), or when they have length greater than 1: outer = 1:2. By default, these cases trigger an error. You can resolve the error by providing a specification that describes how to combine the names or the indices of the inner vector with the name of the input. This specification can be: A function of two arguments. The outer name is passed as a string to the first argument, and the inner names or positions are passed as second argument. An anonymous function as a purrr-style formula. A glue specification of the form "{outer}_{inner}". "inner", in which case outer names are ignored, and inner names are used if they exist. Note that outer names may still be used to provide informative error messages. An rlang::zap() object, in which case both outer and inner names are ignored and the result is unnamed. See the name specification topic.
name_repair	How to repair names, see repair options in vec_as_names().

Value

A vector of type vec_ptype_common(!!!x), or ptype, if specified. The size is computed as vec_size_common(!!!indices) unless the indices are NULL, in which case the size is vec_size_common(!!!x).
