data.xor

Contains functions to simplify the use of data mining methods (classification, regression, clustering, etc.), for students and beginners in R programming. Various R packages are used and wrappers are built around the main functions, to standardize the use of data mining methods (input/output): it brings a certain loss of flexibility, but also a gain of simplicity. The package name came from the French "Fouille de Données en Master 2 Informatique Décisionnelle".

data.xor function

<dl><dt>n</dt>
<dd>Number of observations in each cluster.</dd>
<dt>ndim</dt>
<dd>The number of dimensions (2^ndim clusters are formed, grouped into two classes).</dd>
<dt>sigma</dt>
<dd>The variance.</dd>
<dt>levels</dt>
<dd>Name of each class.</dd>
<dt>graph</dt>
<dd>Whether the generated dataset is plotted. <code>FALSE</code> by default, as
everywhere else in the package: a generator has to be callable in a loop or a report
without piling up graphics devices.</dd>
<dt>seed</dt>
<dd>A specified seed for random number generation.</dd></dl>
