From spray v1.0-7

##### Random spray objects

Creates random spray objects as quick-and-dirty examples of multivariate polynomials

- Keywords
- symbolmath

##### Usage

`rspray(n, vals = 1, arity = 3, powers = 0:2)`

##### Arguments

- n
Number of distinct rows (maximum); repeated rows are merged (argument

`addrepeats`

is`TRUE`

)- vals
Values to use for coefficients

- arity
Arity of the spray; the number of columns in the index matrix

- powers
Set from which to sample the entries of the index matrix

##### Value

Returns a spray object

##### Note

If the index matrix contains repeated rows, the returned spray object
will contain fewer than `n`

entries

##### Examples

```
# NOT RUN {
rspray(10)
rspray(4)*rspray(3,rnorm(3))
rspray(3,arity=7,powers=-2:2)^3
rspray(1000,vals=rnorm(1000))
# }
```
