text2mapping function

<dl><dt>text</dt>
<dd>A multi-line string specifying a mapping with 2 columns (see examples).</dd>
<dt>file</dt>
<dd>If <code>text</code> is missing, read from this file instead.</dd>
<dt>sep</dt>
<dd>Character used as column separator.</dd>
<dt>flip</dt>
<dd>If <code>TRUE</code>, flip the column order to To, From (default <code>FALSE</code>).</dd>
<dt>convert.na</dt>
<dd>If <code>TRUE</code>, the string <code>"NA"</code> will be converted to
<code>NA</code>.</dd>
<dt>numericWherePossible</dt>
<dd>If <code>TRUE</code>, the mapping will return a
<code>numeric</code> vector if the codomain contains only numbers.</dd>
<dt>...</dt>
<dd>Further arguments passed to <code>mapping()</code>.</dd></dl>
