chop a vector — vctrs-vec_chop • plyxp

A re-export of vctrs::vec_chop as an S7 generic function to allow S4Vectors.

Usage

vec_chop(x, ..., indices = NULL)

Arguments

x: A vector
...: These dots are for future extensions and must be empty.
indices: A list of positive integer vectors to slice x with, or NULL. Can't be used if sizes is already specified. If both indices and sizes are NULL, x is split into its individual elements, equivalent to using an indices of as.list(vec_seq_along(x)).

Value

a S3 or S4 vector

Examples

vec_chop(1L)
#> [[1]]
#> [1] 1
#> 
vec_chop(S4Vectors::Rle(c(rep(1, 3), rep(4, 5))), indices = list(c(2, 3, 4), c(1, 5:8)))
#> [[1]]
#> numeric-Rle of length 3 with 2 runs
#>   Lengths: 2 1
#>   Values : 1 4
#> 
#> [[2]]
#> numeric-Rle of length 5 with 2 runs
#>   Lengths: 1 4
#>   Values : 1 4
