rnn is an open-source machine learning framework that implements Recurrent Neural Network architectures, such as LSTM and GRU, natively in the R programming language.
The rnn package is distributed through the Comprehensive R Archive Network[1] under the open-source GPL v3 license.
Workflow
The below example from the rnn documentation show how to train a recurrent neural network to solve the problem of bit-by-bit binary addition.
> # install the rnn package, including the dependency sigmoid
> install.packages('rnn')
> # load the rnn package
> library(rnn)
> # create input data
> X1 = sample(0:127, 10000, replace=TRUE)
> X2 = sample(0:127, 10000, replace=TRUE)
> # create output data
> Y <- X1 + X2
> # convert from decimal to binary notation
> X1 <- int2bin(X1, length=8)
> X2 <- int2bin(X2, length=8)
> Y <- int2bin(Y, length=8)
> # move input data into single tensor
> X <- array( c(X1,X2), dim=c(dim(X1),2) )
> # train the model
> model <- trainr(Y=Y,
+ X=X,
+ learningrate = 1,
+ hidden_dim = 16 )

sigmoid
The sigmoid functions and derivatives used in the package were originally included in the package, from version 0.8.0 onwards, these were released in a separate R package sigmoid, with the intention to enable more general use. The sigmoid package is a dependency of the rnn package and therefore automatically installed with it.[2]
Reception
With the release of version 0.3.0 in April 2016[3] the use in production and research environments became more widespread. The package was reviewed several months later on the R blog The Beginner Programmer as "R provides a simple and very user friendly package named rnn for working with recurrent neural networks.",[4] which further increased usage.[5]
The book Neural Networks in R by Balaji Venkateswaran and Giuseppe Ciaburro uses rnn to demonstrate recurrent neural networks to R users.[6]
The RStudio CRAN mirror download logs [7] show that the package is downloaded on average about 1000 per month from those servers ,[8] with a total of over 20,000 downloads since the first release ,[9] according to RDocumentation.org, this puts the package in the 15th percentile of most popular R packages .[10]
