internal

Creates stratum orthogonal arrays (also known as strong orthogonal arrays). These are arrays with more levels per column than the typical orthogonal array, and whose low order projections behave like orthogonal arrays, when collapsing levels to coarser strata. Details are described in Groemping (2022) "A unifying implementation of stratum (aka strong) orthogonal arrays" <http://www1.bht-berlin.de/FB_II/reports/Report-2022-002.pdf>.

soa function

<dl><dt>oa</dt>
<dd>matrix or data.frame that contains an ingoing symmetric OA. Levels must be denoted as 0 to s-1 or as 1 to s.</dd>
<dt>t</dt>
<dd>the strength the SOA should have, can be 2, 3, 4, or 5. Must not
be larger than the strength of <code>oa</code>, but can be smaller. The resulting SOA will have s^t levels</dd>
<dt>m</dt>
<dd>the requested number of columns (see details for permitted numbers of columns)</dd>
<dt>permlist</dt>
<dd>list of lists of permutations</dd>
<dt>random</dt>
<dd>logical</dd></dl>
