  replace = TRUE
)

(Scalar integer: [1, Inf])
The number of elements in the character vector.

nchars

(Scalar integer: [1, Inf])
The number of characters in each string.

as_raw

(Integer vector: See 'Details')
Integers to be converted to raw type and then back to character.

replace

(Scalar logical: c(TRUE, FALSE))
