# fardist

From spatstat v1.42-2
by Adrian Baddeley

##### Farthest Distance to Boundary of Window

Computes the farthest distance from each pixel, or each data point, to the boundary of the window.

##### Usage

`fardist(X, ...)` ## S3 method for class 'owin':
fardist(X, \dots, squared=FALSE)

## S3 method for class 'ppp':
fardist(X, \dots, squared=FALSE)

##### Arguments

- X
- A spatial object such as a window or point pattern.
- ...
- Arguments passed to
`as.mask`

to determine the pixel resolution, if required. - squared
- Logical. If
`TRUE`

, the squared distances will be returned.

##### Details

The function `fardist`

is generic, with methods for
the classes `owin`

and `ppp`

.

For a window `W`

, the command `fardist(W)`

returns a pixel image in which the value at each pixel
is the *largest* distance from that pixel to the boundary of
`W`

.

For a point pattern `X`

, with window `W`

, the
command `fardist(X)`

returns a numeric vector
with one entry for each point of `X`

, giving the
largest distance from that data point to the boundary of `W`

.

##### Value

- For
`fardist.owin`

, a pixel image (object of class`"im"`

).For

`fardist.ppp`

, a numeric vector.

##### Examples

```
fardist(cells)
plot(FR <- fardist(letterR))
```
