```{r echo=FALSE, results = 'asis'}
pkg <- 'streamMOA'

source("https://raw.githubusercontent.com/mhahsler/pkg_helpers/main/pkg_helpers.R")
pkg_title(pkg)
```

Interface for data stream clustering algorithms implemented in the MOA (Massive Online Analysis) framework. This is an extension package for [stream](https://github.com/mhahsler/stream).

```{r echo=FALSE, results = 'asis'}
pkg_install(pkg)
```

## Example

Create 3 clusters with 5% noise.

```{r}
library(streamMOA)

stream <- DSD_Gaussians(k=3, d=2, noise=.05)
```

Cluster with CluStream.

```{r}
clustream <- DSC_CluStream(m = 50, k = 3)
update(clustream, stream, 500)
clustream
```

Plot micro-clusters.

```{r plot}
plot(clustream, stream)
```
