read.dataset: Reads a KEEL, ARFF or CSV data format file.
In SIMIDAT/SDEFSR: Subgroup Discovery Algorithms for R

Description Usage Arguments Details Author(s) References See Also Examples

This function reads a KEEL (.dat), ARFF (.arff) or CSV dataset file and store the information in a SDEFSR_Dataset class.

1 2	read.dataset(file, sep = ",", quote = "\"", dec = ".", na.strings = "?")

`file`	The path of the file to read
`sep`	The separator character to use
`quote`	The character used to take quotes
`dec`	The character used to define decimal characters
`na.strings`	The character to detect lost data

A KEEL data file must have the following structure:

@relation: Name of the data set
@attribute: Description of an attribute (one for each attribute)
@inputs: List with the names of the input attributes
@output: Name of the output attribute (Not used in this algorithms implementation)
@data: Starting tag of the data

The rest of the file contains all the examples belonging to the data set, expressed in comma sepparated values format. ARFF file format is a well-know dataset format from WEKA data mining tool. CSV is a format which means comma-separated values. Where each examples is on a line and each value of the variables of the examples are separated by commas.
