ord.rw

Re-computes an ordination using given row weights (possibly extracted from a correspondence analysis). The function is intended to be used prior to <code>coinertia</code> when row weights have to be equalized.

Contains miscellaneous functions useful in biostatistics, mostly univariate and multivariate testing procedures with a special emphasis on permutation tests. Many functions intend to simplify user's life by shortening existing procedures or by implementing plotting functions that can be used with as many methods from different packages as possible.

<dl> <dt>ord</dt>
<dd>an ordination to re-compute. Must come from the <code>ade4</code> package or be supported by <code>to.dudi</code>. In any case the resulting ordination will be in the <code>ade4</code> format.</dd> <dt>CA</dt>
<dd>an optional correspondence analysis from which row weights should be extracted. Must come from <code>dudi.coa</code> or <code>cca</code>.</dd> <dt>rw</dt>
<dd>an optional vector of row weights. Used only is <code>CA</code> is <code>NULL</code>.</dd></dl>
