random.range

It is used within other functions in this package to
 radomly place given number of species occurrences

Used for generating randomized community matrices under
strict range cohesion. The package can handle data where species occurrence
are recorded across sites ordered along gradients such as elevation and latitude, as well as species occurrences recorded on spatial grids with known geographic coordinates.

random.range function

<dl><dt>uid</dt>
<dd>a vector of unique ids for selection</dd>
