%description
The Stuttgart Neural Network Simulator (SNNS) is a library containing many
standard implementations of neural networks. This package wraps the SNNS
functionality to make it available from within R. Using the 'RSNNS'
low-level interface, all of the algorithmic functionality and flexibility
of SNNS can be accessed. Furthermore, the package contains a convenient
high-level interface, so that the most common neural network topologies
and learning algorithms integrate seamlessly into R.
