Create `n`

new `turtles`

on specific `patches`

.

```
sprout(n, patches, breed, heading, color, turtles)
# S4 method for numeric,matrix
sprout(n, patches, breed, heading, color, turtles)
```

## Arguments

- n
Integer. Vector of length 1 or of length the number of `patches`

.
Number of new `turtles`

to create on each `patch`

.

- patches
Matrix (`ncol`

= 2) with the first column `pxcor`

and the second
column `pycor`

representing the `patches`

coordinates.

- breed
Character. Vector of `breed`

names.
Must be of length 1 or of length the number of `patches`

.
If missing, `breed`

= `turtle`

for all the sprouted `turtles`

.

- heading
Numeric. Vector of values between 0 and 360.
Must be of length 1 or of length the number of `patches`

.
If missing, a random `heading`

is assigned to each sprouted `turtle`

.

- color
Character. Vector of `color`

names.
Must be of length 1, of length the number of `patches`

or
of length `sum(n)`

.
If missing, `colors`

are assigned using the function `rainbow(n)`

.

- turtles
`AgentMatrix`

object representing the moving `agents`

.

## Value

`AgentMatrix`

including the new
sprouted `turtles`

.

## Details

`nrow(patches)`

must be equal to 1 or to `n`

.

```
If `turtles` is provided, the new `turtles` are added to
the `turtles` when returned. The `who` numbers of the sprouted `turtles`
therefore follow the ones from the `turtles`.
All new sprouted `turtles` are placed at the end of the `agentMatrix` object.
If no `turtles`
is provided, a new `agentMatrix` is created and the `who` numbers
start at 0.
If `turtles` is provided and had additional variables created
with `turtlesOwn()`, `NA` is given for these variables
for the new sprouted `turtles`.

```
t1 <- sprout(patches = cbind(pxcor = 2, pycor = 2), n = 3)
t2 <- sprout(patches = cbind(pxcor = 3, pycor = 3), n = 3, turtles = t1)
