Create a pattern recognition data set from text files stored in directories. Each of the text files are read in from each directory (and assigned the appropriate class), with the files text being converted into a String and used as an attribute! Really this is useful for applications such as creating data sets from email/documents etc. Will strip out the charachter ' so that can output as a string in arff format!

Parameters:

dataSetName - the name of the data set that you are creating

stringAttributeName - the name of the String attribute that you are creating!

directoryNames - an array contains vectors of each directory name (containing the files for each class)

Returns:

the nice data set all in friendly arff format

java.lang.Exception

Parameters:

inputFile - the input file to be converted
