R: Test Whether Function Objects Are Compatible

compatible.fv {spatstat} | R Documentation

## Test Whether Function Objects Are Compatible

### Description

Tests whether two or more function objects (class `"fv"`) are compatible.

### Usage

      ## S3 method for class 'fv'
    compatible(A, B, ..., samenames=TRUE)

### Arguments

`A,B,...` | Two or more function value objects (class `"fv"`).
`samenames` | Logical value indicating whether to check for complete agreement between the column names of the objects (`samenames=TRUE`, the default) or just to check that the name of the function argument is the same (`samenames=FALSE`).

### 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.
