Description of statistical associations between two variables : measures of local and global association between variables (phi, Cramér V, correlations, eta-squared, Goodman and Kruskal tau, permutation tests, etc.), multiple graphical representations of the associations between two variables (using 'ggplot2') and weighted statistics.

<dd>an optional data frame of numeric vectors. Default is NULL, which means that covariances between the columns of <code>x</code> are computed.</dd> <dt>weights</dt>
<dd>numeric vector of weights. If NULL (default), uniform weights (i.e. all equal to 1) are used.</dd> <dt>na.rm</dt>
