DSD_Target: Target Data Stream Generator
Description
A data stream generator that generates a data stream in the shape of a target.
It has a single Gaussian cluster in the center and a ring that surrounds it.
Usage
DSD_Target(center_sd = 0.05, center_weight = 0.5, ring_r = 0.2, ring_sd = 0.02, noise = 0)
Arguments
center_sd
standard deviation of center
center_weight
proportion of points in center
ring_r
average ring radius
ring_sd
standard deviation of ring radius
Value
Returns a DSD_Target
object which is a list of the defined
params. The params are either passed in from the function or
created internally. They include:
Details
DSD_Target
is a DSD generator for stream data.
It has been implemented entirely in R, so there is no computational
overhead with communicating to the Java Runtime Interface (JRI) or
native C code. This DSD will produce a singular Gaussian cluster in the
center with a ring around it.
Examples
Run this code# create data stream with three clusters in 2D
stream <- DSD_Target()
# plotting the data
plot(stream)
