<h3>Arguments</h3>

<table summary="R argblock">
<tr valign="top"><td><code>x</code></td>
<td>
<p>object of class <code>bbox</code></p>
</td></tr>
<tr valign="top"><td><code>obj</code></td>
<td>
<p>object to compute the bounding box from</p>
</td></tr>
<tr valign="top"><td><code>...</code></td>
<td>
<p>for format.bbox, passed on to <a href="../../base/html/format.html">format</a> to format individual numbers</p>
</td></tr>
<tr valign="top"><td><code>crs</code></td>
<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>bbox</code> of length 4.
</p>

<h3>Details</h3>

<p><code>NA_bbox_</code> represents the missing value for a <code>bbox</code> object
</p>

<h3>Value</h3>

<p>a numeric vector of length four, with <code>xmin</code>, <code>ymin</code>, <code>xmax</code>
and <code>ymax</code> values; if <code>obj</code> is of class <code>sf</code>, <code>sfc</code>, <code>Spatial</code> or <code>Raster</code>, the object
returned has a class <code>bbox</code>, an attribute <code>crs</code> and a method to print the
bbox and an <code>st_crs</code> method to retrieve the coordinate reference system
corresponding to <code>obj</code> (and hence the bounding box). <a href="st_as_sfc.html">st_as_sfc</a> has a
methods for <code>bbox</code> objects to generate a polygon around the four bounding box points.
</p>

<h3>Examples</h3>

<pre>
a = st_sf(a = 1:2, geom = st_sfc(st_point(0:1), st_point(1:2)), crs = 4326)
st_bbox(a)
st_as_sfc(st_bbox(a))
st_bbox(c(xmin = 16.1, xmax = 16.6, ymax = 48.6, ymin = 47.9), crs = st_crs(4326))
