##### Approximate Pair Correlation Function of Determinantal Point Process Model

Returns an approximation to the theoretical pair correlation function of a determinantal point process model, as a function of one argument \(x\).

##### Usage

`dppapproxpcf(model, trunc = 0.99, W = NULL)`

##### Arguments

- model
Object of class

`"detpointprocfamily"`

.- trunc
Numeric specifying how the model truncation is performed. See Details section of

`simulate.detpointprocfamily`

.- W
Optional window -- undocumented at the moment.

##### Details

This function is usually NOT needed for anything. It only exists for investigative purposes.

##### Examples

```
# NOT RUN {
f <- dppapproxpcf(dppMatern(lambda = 100, alpha=.028, nu=1, d=2))
plot(f, xlim = c(0,0.1))
# }
```
