<p>I'm looking at <a href="https://stats.stackexchange.com/questions/57157/calculate-mean-of-one-variable-while-controlling-for-another-using-regression">this page</a>, which includes an R expression (for the gam function in the mgcv package). The R expression includes two elements (functions?) which do not appear on the help page for that function ('te' and 'bs').</p>
<p>R, of course, almost glories in its perverse unsearchability - a Google search on &quot;te&quot; brings up 4.6bn results!</p>
<p>The obvious resort would be to comment on the answer, asking for clarification.</p>
<p>However, as I understand it, those with fewer than 50 points in the bank are barred from doing this, and needs must remain in ignorance.</p>
<p>Is this a bug or a feature?</p>
