# fardist

##### 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 owin
fardist(X, …, squared=FALSE)

# S3 method for ppp
fardist(X, …, 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

```
# NOT RUN {
fardist(cells)
plot(FR <- fardist(letterR))
# }
```
