<dl> <dt>origpos</dt>
<dd>a vector of original position values.</dd> <dt>newpos</dt>
<dd>a vector of new positions to align or interpolate it to.</dd> <dt>how</dt>
<dd>specifies how to treat unmatched positions. Must be one of the following:<table class="table">
<tr><td><code>"NA"</code></td><td>Insert a row of <code>NA</code>.</td></tr>
<tr><td><code>"drop"</code></td><td>Drop that position entirely.</td></tr>
<tr><td><code>"nearest"</code></td><td>Use the row with the nearest position.</td></tr>
<tr><td><code>"before"</code></td><td>Use the data from the row whose position 
is just before the unmatched position.</td></tr>
<tr><td><code>"after"</code></td><td>Use the data from the row whose position is 
just after the unmatched position.</td></tr>
<tr><td><code>"interp"</code></td><td>Interpolate linearly between <code>"before"</code> and <code>"after"</code>.</td></tr>
</table></dd> <dt>error.how</dt>
<dd>specifies available actions when an out of bounds error occurs. (Such an error can occur 
when <code>how</code> is <code>"before"</code>, <code>"after"</code>, or <code>"interp"</code>). Must be one of
the following:<table class="table">
<tr><td><code>"NA"</code></td><td>Insert a row of <code>NA</code>.</td></tr>
<tr><td><code>"drop"</code></td><td>Drop that position entirely.</td></tr>
<tr><td><code>"nearest"</code></td><td>Use the row with the nearest position.</td></tr>

<dd>the tolerance for matching positions.</dd>

`"NA"`	Insert a row of `NA`.
`"drop"`	Drop that position entirely.
`"nearest"`	Use the row with the nearest position.
`"before"`	Use the data from the row whose position is just before the unmatched position.
`"after"`	Use the data from the row whose position is just after the unmatched position.
`"interp"`	Interpolate linearly between `"before"` and `"after"`.

`"NA"`	Insert a row of `NA`.
`"drop"`	Drop that position entirely.
`"nearest"`	Use the row with the nearest position.
