##### Test Whether Function Objects Are Compatible

Tests whether two or more function objects (class `"fv"`

)
are compatible.

##### Usage

```
# S3 method for fv
compatible(A, B, …)
```

##### Arguments

- A,B,…
Two or more function value objects (class

`"fv"`

).

##### Details

An object of class `"fv"`

is essentially a data frame
containing several different statistical estimates of the same
function. Such objects are returned by `Kest`

and its
relatives.

This command tests whether such objects are compatible
(so that, for example, they could be added or subtracted).
It is a method for the generic command `compatible`

.

The functions are compatible if they have been evaluated at the
same sequence of values of the argument `r`

, and if the
statistical estimates have the same names.

##### Value

Logical value: `TRUE`

if the objects are compatible, and `FALSE`

if they are not.
