Set the length of a vector, padding or truncating as needed

Source: R/setLength.R
setLength.Rd

Extends x to length n by appending fill, or truncates it to length n if it is already longer – like length(x) <- n, but with a configurable fill value instead of NA.

Usage

setLength(x, n, fill = NA)

Arguments

x

a vector.

n

target length, a single non-negative whole number.

fill

value used for newly added elements when x is extended (default NA).

Value

x, of length n.

setLength(LETTERS[1:3], 5)
#> [1] "A" "B" "C" NA  NA 
setLength(LETTERS[1:3], 2)
#> [1] "A" "B"
setLength(1:4, 6, fill = 0)
#> [1] 1 2 3 4 0 0
