## Count Number of Geometrical Objects in a Spatial Dataset

### Description

A generic function to count the number of geometrical objects in a spatial dataset.

### Usage

      nobjects(x)

      ## S3 method for class 'ppp'
    nobjects(x)

      ## S3 method for class 'ppx'
    nobjects(x)

      ## S3 method for class 'psp'
    nobjects(x)

      ## S3 method for class 'tess'
    nobjects(x)

### Arguments

`x` | A dataset.

### Details

The generic function `nobjects` counts the number of geometrical objects in the spatial dataset `x`.

The methods for point patterns (classes `"ppp"` and `"ppx"`, embracing `"pp3"` and `"lpp"`) count the number of points in the pattern.

The method for line segment patterns (class `"psp"`) counts the number of line segments in the pattern.

The method for tessellations (class `"tess"`) counts the number of tiles of the tessellation.
