# randomCoordinates

From geosphere v1.5-10
by Robert Hijmans

##### Random or regularly distributed coordinates on the globe

randomCoordinates returns a 'uniform random sample' in the sense that the probability that a point is drawn from any region is equal to the area of that region divided by the area of the entire sphere. This would not happen if you took a random uniform sample of longitude and latitude, as the sample would be biased towards the poles.

regularCoordiaates returns a set of coordinates that are regularly distributed on the globe.

- spatial

##### Usage

```
randomCoordinates(n)
regularCoordinates(N)
```

##### Arguments

- n
Sample size (number of points (coordinate pairs))

- N
Number of 'parts' in which the earth is subdived )

##### Value

Matrix of lon/lat coordiantes

##### Examples

```
# NOT RUN {
randomCoordinates(3)
regularCoordinates(1)
# }
```
