object

an iterable object

fill

the value to pad the indefinite iterator after the initial object is consumed. Default: NA

...

Examples

it <- iteror(1:9)
it_i_pad <- i_pad(it)
as.list(i_slice(it_i_pad, end=9)) # Same as as.list(1:9)

it2 <- iteror(1:9)
it2_i_pad <- i_pad(it2)
as.list(i_slice(it2_i_pad, end=10)) # Same as as.list(c(1:9, NA))

it3 <- iteror(1:9)
it3_i_pad <- i_pad(it3, fill=TRUE)
as.list(i_slice(it3_i_pad, end=10)) # Same as as.list(c(1:9, TRUE))
