## R/Weka File Loaders and Savers

### Description

R interfaces to Weka file loaders and savers.

### Usage

    C45Loader(file)
    XRFFLoader(file)
    C45Saver(x, file, control = NULL)
    XRFFSaver(x, file, control = NULL)

### Arguments

`file` | a non-empty character string naming a file to read from or write to.
`x` | the data to be written, preferably a matrix or data frame. If not, coercion to a data frame is attempted.
`control` | an object of class `Weka_control`, or a character vector of control options, or `NULL` (default). Available options can be obtained on-line using the Weka Option Wizard `WOW`, or the Weka documentation.

### Details

`C45Loader` and `C45Saver` use the format employed by the C4.5 algorithm/software, where data is stored in two separate ‘.names’ and ‘.data’ files.

`XRFFLoader` and `XRFFSaver` handle XRFF (eXtensible attribute-Relation File Format, an XML-based extension of Weka's native Attribute-Relation File Format) files.

### Value

Invisibly `NULL` for the savers.
A data frame containing the data from the given file for the loaders.

### See Also

`read.arff`, `write.arff`.
