<td>
<p>object of class <code>crs</code>, or argument to <a href="st_crs.html">st_crs</a>, specifying the CRS of this bounding box.</p>
</td></tr>
</table>

<h3>Format</h3>

<p>An object of class <code>m_range</code> of length 2.
</p>

<h3>Details</h3>

<p><code>NA_m_range_</code> represents the missing value for a <code>m_range</code> object
</p>

<h3>Value</h3>

<p>a numeric vector of length two, with <code>mmin</code> and <code>mmax</code> values;
if <code>obj</code> is of class <code>sf</code> or <code>sfc</code> the object
if <code>obj</code> is of class <code>sf</code> or <code>sfc</code> the object
returned has a class <code>m_range</code>
</p>

<h3>Examples</h3>

<pre>
a = st_sf(a = 1:2, geom = st_sfc(st_point(0:3), st_point(1:4)), crs = 4326)
st_m_range(a)
st_m_range(c(mmin = 16.1, mmax = 16.6), crs = st_crs(4326))
