fail	[numeric(1) or numeric vector: fill] In case it fails to fill some values.

Examples

x <- c(5,3,2,2,5)

lagx(x, n = 2, fill = fill_locf)
#> [1] NA NA  5  3  2

# A not so very neat way to deal with NA when `fill_locf` fails is
lagx(x, n = 2, fill = ~ fill_locf(.x,.y, fail = 0))
#> [1] 0 0 5 3 2

leadx(x, n = 2, fill = fill_locf)
#> [1] 2 2 5 5 5

lagx(x, n = 2, fill = fill_nocb)
#> [1] 5 5 5 3 2

leadx(x, n = 2, fill = fill_nocb)
#> [1]  2  2  5 NA NA

leadx(x, n = 2, fill = ~ fill_nocb(.x,.y, fail = 0))
#> [1] 2 2 5 0 0
