##### Create A Vector of Sequences

For each element of nvec the sequence seq_len(nvec[i]) is created. These are concatenated and the result returned.

Keywords
manip
##### 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.
