Finds the "previous" (lag) or "next" (lead) values in a vector or object with values at the end of the vector recycled to the beginning.

Finds the "previous" (lag) or "next" (lead) values in a vector or object with values at the end of the vector recycled to the beginning.

Usage

lead_cycle(x, n = 1L)

lag_cycle(x, n = 1L)

Arguments

x

A vector or ggdiagram object

n

Positive integer of length 1, giving the number of positions to lag or lead by

Value

A vector with the same type and size as x but with elements shifted and cycled by n.

Examples

lead_cycle(1:5)
#> [1] 2 3 4 5 1
lead_cycle(1:5, 2)
#> [1] 3 4 5 1 2
lag_cycle(1:5)
#> [1] 5 1 2 3 4
lag_cycle(1:5, 2)
#> [1] 4 5 1 2 3
