# S3 method for integer64
seq(from = NULL, to = NULL, by = NULL, length.out = NULL, along.with = NULL, …)
integer64 scalar (in order to dispatch the integer64 method of seq
an integer64 vector with the generated sequence
seq.integer64 does coerce its arguments 'from', 'to' and 'by' to integer64.
If not provided, the argument 'by' is automatically determined as +1 or -1,
but the size of 'by' is not calculated as in seq (because this might result in a non-integer value).
