response {spatstat.core} | R Documentation

## Extract the Values of the Response from a Fitted Model

### Description

Given a fitted model (of any kind) extract the values of the response variable.

### Usage

    response(object)

    ## S3 method for class 'lm'
    response(object)

    ## S3 method for class 'glm'
    response(object)

    ## S3 method for class 'ppm'
    response(object)

    ## S3 method for class 'kppm'
    response(object)

    ## S3 method for class 'dppm'
    response(object)

    ## S3 method for class 'slrm'
    response(object)

    ## S3 method for class 'mppm'
    response(object)

### Arguments

`object` | A fitted model (object of class `"lm"`, `"glm"`, `"ppm"`, `"kppm"`, `"dppm"`, `"slrm"` or `"mppm"` or some other class).

### Details

For fitted linear models of class `"lm"` and fitted generalized linear models of class `"glm"`, the numerical values of the response variable are extracted if they are available, and otherwise `NULL` is returned.

For fitted point process models of class `"ppm"`, `"kppm"`, `"dppm"`, `"slrm"` or `"lppm"`, the original data point pattern is extracted.

For a fitted point process model of class `"mppm"`, the list of original data point patterns is extracted.

### Value

For `response.lm` and `response.glm`, a numeric vector, or `NULL`.

For `response.ppm`, `response.kppm`, `response.dppm` and `response.slrm` a two-dimensional spatial point pattern (class `"ppp"`).

For `response.mppm`, a list of two-dimensional spatial point patterns (objects of class `"ppp"`). The list also belongs to classes `"solist"` and `"ppplist"`.
