`snns': R <=> SNNS Interface

This package provides the start for an R interface to the Stuttgart
Neural Network Simulator (SNNS). Currently it only provides means to
read, write and analyze pattern and result files of SNNS. Thus you can
preprocess your data using R (normalize, ...), then write an SNNS
pattern file, train a net on it and finally load the result back
into R to evaluate the outcome.

Currently there is no support for variable input/output dimensions,
but I'm planning to support these soon. Maybe there will also be an
interface for training nets directly from R in the future, but
currently I have no time for this. Any volunteers?

You need the following for this library to work:
1) the e0171 contrib package:
	also provided at our ftp archive (see below)
2) perl
	used for parsing result and pattern files
	(res2r and pat2r in the cmd directory are perl scripts)

3) mkhead
	an SNNS utility for writing pattern headers, this should come
	with your copy of SNNS.



INSTALLATION NOTE:
You have to copy all files from the cmd subdirectory to your
$RHOME/cmd directory MANUALLY. Otherwise install like any other R
package.



The latest version of this package can always be downloaded from

  ftp://ftp.ci.tuwien.ac.at/pub/export/R/source/contrib
