Examples

v <- 1:3
x <- 0
insert_vector_entry(v, x, 0)
#> [1] 0 1 2 3
insert_vector_entry(v, x, 1)
#> [1] 1 0 2 3
insert_vector_entry(v, x, 2)
#> [1] 1 2 0 3
insert_vector_entry(v, x, 3)
#> [1] 1 2 3 0

### also multiple positions
insert_vector_entry(v, x, 0:3)
#> [1] 0 1 0 2 0 3 0

### also trivial case
insert_vector_entry(integer(), integer(), integer())
#> integer(0)
