bhtsneR

=======

A minimal, CRAN-compliant wrapper for the Barnes-Hut implementation of 

[T-distributed Stochastic Neighbor Embedding (t-SNE)](http://homepage.tudelft.nl/19j49/t-SNE.html).

### Installation

You will need the following software:

 * [cblas](http://www.netlib.org/blas/) or [openblas](https://github.com/xianyi/OpenBLAS)

 * R packages: `Rcpp`, `devtools`

Run this in R to install the current GitHub version:

```splus

devtools::install_github("mschubert/bhtsneR")

```

### Running

Here is an example on how to run it on the iris data set:

```splus

library(bhtsneR)

# perform Barnes-Hut t-SNE

result = bhtsne(iris[1:4])

plot(result, col=iris[[5]])

# perform exact calculations

# this is equivalent to bhtsne(..., theta=0)

result = tsne(iris[1:4])

plot(result, col=iris[[5]])

```
