DSD_Mixture {stream}

Mixes Data Points from Several Streams into a Single Stream

Description

This generator mixes multiple streams given specified probabilities. The streams have to contain the same number of dimensions.

Usage

DSD_Mixture(..., prob = NULL)

Arguments

...

DSD objects.

prob

a numeric vector with the probability for each stream that the next point will be drawn from that stream.

Value

Returns a DSD_Mixture object.(subclass of DSD_R, DSD).

stream1 <- DSD_Gaussians(d = 2, k = 3)
stream2 <- DSD_UniformNoise(d = 2,  range = rbind(c(-.5, 1.5), c(-.5, 1.5)))

combinedStream <- DSD_Mixture(stream1, stream2, prob = c(.9, .1))
