Each case draws a single graphical object. </p> <h3>Usage</h3> <pre> geom_crossbar( mapping = NULL, data = NULL, stat = "identity", position = "identity", ..., fatten = 2.5, na.rm = FALSE, orientation = NA, show.legend = NA, inherit.aes = TRUE ) geom_errorbar( mapping = NULL, data = NULL, stat = "identity", position = "identity", ..., na.rm = FALSE, orientation = NA, show.legend = NA, inherit.aes = TRUE ) geom_linerange( mapping = NULL, data = NULL, stat = "identity", position = "identity", ..., na.rm = FALSE, orientation = NA, show.legend = NA, inherit.aes = TRUE ) geom_pointrange( mapping = NULL, data = NULL, stat = "identity", position = "identity", ..., fatten = 4, na.rm = FALSE, orientation = NA, show.legend = NA, inherit.aes = TRUE ) </pre> <h3>Arguments</h3> <table summary="R argblock"> <tr valign="top"><td><code>mapping</code></td> <td> <p>Set of aesthetic mappings created by <code><a href="aes.html">aes()</a></code> or <code><a href="aes_.html">aes_()</a></code>. If specified and <code>inherit.aes = TRUE</code> (the default), it is combined with the default mapping at the top level of the plot. You must supply <code>mapping</code> if there is no plot mapping.</p> </td></tr> <tr valign="top"><td><code>data</code></td> <td> <p>The data to be displayed in this layer. There are three options: </p> <p>If <code>NULL</code>, the default, the data is inherited from the plot data as specified in the call to <code><a href="ggplot.html">ggplot()</a></code>. </p> <p>A <code>data.frame</code>, or other object, will override the plot data. All objects will be fortified to produce a data frame. See <code><a href="fortify.html">fortify()</a></code> for which variables will be created. </p> <p>A <code>function</code> will be called with a single argument, the plot data. The return value must be a <code>data.frame</code>, and will be used as the layer data. A <code>function</code> can be created from a <code>formula</code> (e.g. <code>~ head(.x, 10)</code>).</p> </td></tr> <tr valign="top"><td><code>stat</code></td> <td> <p>The statistical transformation to use on the data for this layer, as a string.</p> </td></tr> <tr valign="top"><td><code>position</code></td> <td> <p>Position adjustment, either as a string, or the result of a call to a position adjustment function.</p> </td></tr> <tr valign="top"><td><code>...</code></td> <td> <p>Other arguments passed on to <code><a href="layer.html">layer()</a></code>. These are often aesthetics, used to set an aesthetic to a fixed value, like <code>colour = "red"</code> or <code>size = 3</code>. They may also be parameters to the paired geom/stat.</p> </td></tr> <tr valign="top"><td><code>fatten</code></td> <td> <p>A multiplicative factor used to increase the size of the middle bar in <code>geom_crossbar()</code> and the middle point in <code>geom_pointrange()</code>.</p> </td></tr> <tr valign="top"><td><code>na.rm</code></td> <td> <p>If <code>FALSE</code>, the default, missing values are removed with a warning. If <code>TRUE</code>, missing values are silently removed.</p> </td></tr> <tr valign="top"><td><code>orientation</code></td> <td> <p>The orientation of the layer. The default (<code>NA</code>) automatically determines the orientation from the aesthetic mapping. In the rare event that this fails it can be given explicitly by setting <code>orientation</code> to either <code>"x"</code> or <code>"y"</code>. See the <em>Orientation</em> section for more detail.</p> </td></tr> <tr valign="top"><td><code>show.legend</code></td> <td> <p>logical. Should this layer be included in the legends? <code>NA</code>, the default, includes if any aesthetics are mapped. <code>FALSE</code> never includes, and <code>TRUE</code> always includes. It can also be a named logical vector to finely select the aesthetics to display.</p> </td></tr> <tr valign="top"><td><code>inherit.aes</code></td> <td> <p>If <code>FALSE</code>, overrides the default aesthetics, rather than combining with them. This is most useful for helper functions that define both data and aesthetics and shouldn't inherit behaviour from the default plot specification, e.g. <code><a href="borders.html">borders()</a></code>.</p> </td></tr> </table> <h3>Orientation</h3> <p>This geom treats each axis differently and, thus, can thus have two orientations. Often the orientation is easy to deduce from a combination of the given mappings and the types of positional scales in use. Thus, ggplot2 will by default try to guess which orientation the layer should have. Under rare circumstances, the orientation is ambiguous and guessing may fail. In that case the orientation can be specified directly using the <code>orientation</code> parameter, which can be either <code>"x"</code> or <code>"y"</code>. The value gives the axis that the geom should run along, <code>"x"</code> being the default orientation you would expect for the geom. </p> <h3>Aesthetics</h3> <p><code>geom_linerange()</code> understands the following aesthetics (required aesthetics are in bold): </p> <ul> <li> <p><strong><code>x</code> <em>or</em> <code>y</code></strong> </p> </li> <li> <p><strong><code>ymin</code> <em>or</em> <code>xmin</code></strong> </p> </li> <li> <p><strong><code>ymax</code> <em>or</em> <code>xmax</code></strong> </p> </li> <li> <p><code>alpha</code> </p> </li> <li> <p><code>colour</code> </p> </li> <li> <p><code>group</code> </p> </li> <li> <p><code>linetype</code> </p> </li> <li> <p><code>size</code> </p> </li></ul> <p>Learn more about setting these aesthetics in <code>vignette("ggplot2-specs")</code>. </p> <h3>See Also</h3> <p><code><a href="stat_summary.html">stat_summary()</a></code> for examples of these guys in use, <code><a href="geom_smooth.html">geom_smooth()</a></code> for continuous analogue, <code><a href="geom_errorbarh.html">geom_errorbarh()</a></code> for a horizontal error bar. </p> <h3>Examples</h3> <pre> # Create a simple example dataset df <- data.frame( trt = factor(c(1, 1, 2, 2)), resp = c(1, 5, 3, 4), group = factor(c(1, 2, 1, 2)), upper = c(1.1, 5.3, 3.3, 4.2), lower = c(0.8, 4.6, 2.4, 3.6) ) p <- ggplot(df, aes(trt, resp, colour = group)) p + geom_linerange(aes(ymin = lower, ymax = upper)) p + geom_pointrange(aes(ymin = lower, ymax = upper)) p + geom_crossbar(aes(ymin = lower, ymax = upper), width = 0.2) p + geom_errorbar(aes(ymin = lower, ymax = upper), width = 0.2) # Flip the orientation by changing mapping ggplot(df, aes(resp, trt, colour = group)) + geom_linerange(aes(xmin = lower, xmax = upper)) # Draw lines connecting group means p + geom_line(aes(group = group)) + geom_errorbar(aes(ymin = lower, ymax = upper), width = 0.2) # If you want to dodge bars and errorbars, you need to manually # specify the dodge width p <- ggplot(df, aes(trt, resp, fill = group)) p + geom_col(position = "dodge") + geom_errorbar(aes(ymin = lower, ymax = upper), position = "dodge", width = 0.25) # Because the bars and errorbars have different widths # we need to specify how wide the objects we are dodging are dodge <- position_dodge(width=0.9) p + geom_col(position = dodge) + geom_errorbar(aes(ymin = lower, ymax = upper), position = dodge, width = 0.25) # When using geom_errorbar() with position_dodge2(), extra padding will be # needed between the error bars to keep them aligned with the bars. p + geom_col(position = "dodge2") + geom_errorbar( aes(ymin = lower, ymax = upper), position = position_dodge2(width = 0.5, padding = 0.5) ) </pre> <hr /><div style="text-align: center;">[Package <em>ggplot2</em> version 3.3.2 <a href="00Index.html">Index</a>]</div> </body></html>
