scatterplot

Produce a scatter plot for clustering results. If the dataset has more than two dimensions, the scatter plot will show the two first PCA axes.

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".

scatterplot function

<dl><dt>d</dt>
<dd>The dataset (<code>matrix</code> or <code>data.frame</code>).</dd>
<dt>clusters</dt>
<dd>Cluster labels of the training set: a numeric <code>vector</code> (0 marking the
observations a density method left as noise), or a <code>factor</code>/character vector, whose
levels are then used to label the legend.</dd>
<dt>centers</dt>
<dd>Coordinates of the cluster centers.</dd>
<dt>labels</dt>
<dd>Indicates whether or not labels (row names) should be showned on the plot.</dd>
<dt>ellipses</dt>
<dd>Indicates whether or not ellipses should be drawned around clusters.</dd>
<dt>legend</dt>
<dd>Indicates where the legend is placed on the graphics.</dd>
