Data Stream Data Generator Base Classes

Description

Abstract base classes for DSD (Data Stream Data Generator).

Usage

DSD(...)

DSD_R(...)

Arguments

...

further arguments.

Details

The DSD class cannot be instantiated, but it serves as a abstract base class from which all DSD objects inherit. Implementations can be found in the See Also section below.

DSD provides common functionality like:

DSD_R inherits form DSD and is the abstract parent class for DSD implemented in R. To create a new R-based implementation there are only two function that needs to be implemented for a new DSD subclass called Foo would be:

  1. A creator function DSD_Foo(...) and

  2. a method get_points.DSD_Foo(x, n = 1L) for that class.

Examples

DSD()

# create data stream with three clusters in 3-dimensional space
stream <- DSD_Gaussians(k = 3, d = 3)

# get points from stream
get_points(stream, n = 5)

# plotting the data (scatter plot matrix, first and third dimension, and first
#  two principal components)
plot(stream)
plot(stream, dim = c(1, 3))
plot(stream, method = "pca")
