new-vector-along {rlang}R Documentation

Create vectors matching the length of a given vector

Description

These functions take the idea of seq_along() and generalise it to creating lists (new_list_along) and repeating values (rep_along). Except for new_list_along() and new_raw_along(), the empty vectors are filled with typed missing values.

Usage

new_logical_along(x, names = base::names(x))

new_integer_along(x, names = base::names(x))

new_double_along(x, names = base::names(x))

new_character_along(x, names = base::names(x))

new_complex_along(x, names = base::names(x))

new_raw_along(x, names = base::names(x))

new_list_along(x, names = base::names(x))

rep_along(.x, .y)

Arguments

x, .x

A vector.

names

Names for the new vector. Defaults to the names of x. This can be a function to apply to the names of x as in set_names().

.y

Values to repeat.

Examples

x <- 0:5
rep_along(x, 1:2)
rep_along(x, 1)
new_list_along(x)

# The default names are picked up from the input vector
x <- c(a = "foo", b = "bar")
new_character_along(x)
