# sample_seq

From igraph v1.2.5

##### Sampling a random integer sequence

This function provides a very efficient way to pull an integer random sample sequence from an integer interval.

- Keywords
- datagen

##### Usage

`sample_seq(low, high, length)`

##### Arguments

- low
The lower limit of the interval (inclusive).

- high
The higher limit of the interval (inclusive).

- length
The length of the sample.

##### Details

The algorithm runs in `O(length)`

expected time, even if
`high-low`

is big. It is much faster (but of course less general) than
the builtin `sample`

function of R.

##### Value

An increasing numeric vector containing integers, the sample.
