# R wrapper for Van der Maaten's Barnes-Hut implementation of t-Distributed Stochastic Neighbor Embedding 

## Installation

To install from CRAN:

```{r, eval = FALSE}

install.packages("Rtsne") # Install Rtsne package from CRAN

```

To install the latest version from the github repository, use:

```{r, eval = FALSE}

if(!require(devtools)) install.packages("devtools") # If not already installed

devtools::install_github("jkrijthe/Rtsne")

```

## Usage

After installing the package, use the following code to run a simple example (to install, see below).

```{r example, fig.path="tools/"}

library(Rtsne) # Load package

iris_unique <- unique(iris) # Remove duplicates

set.seed(42) # Sets seed for reproducibility

tsne_out <- Rtsne(as.matrix(iris_unique[,1:4])) # Run TSNE

plot(tsne_out$Y,col=iris_unique$Species,asp=1) # Plot the result

```

# Details

This R package offers a wrapper around the Barnes-Hut TSNE C++ implementation of [2] [3]. Changes were made to the original code to allow it to function as an R package and to add additional functionality and speed improvements.
