is created. These are concatenated and the result returned.

Usage
sequence(nvec)Arguments
- nvec
a non-negative integer vector each element of which specifies the end point of a sequence.
Details
Earlier versions of sequence used to work for 0 or negative inputs as
seq(x) == 1:x.
Note that sequence <- function(nvec) unlist(lapply(nvec, seq_len))
and it mainly exists in reverence to the very early history of R.
