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

Installation

To install from CRAN:

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

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

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).

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.
