The examples demonstrate their use with x scales, but they work similarly for all scales, including those that generate legends rather than axes. </p> <h3>Old interface</h3> <p><code>pvalue()</code> and <code>pvalue_dollar()</code> are retired; please use <code>label_pvalue()</code> instead. </p> <h3>See Also</h3> <p>Other labels for continuous scales: <code><a href="label_bytes.html">label_bytes</a>()</code>, <code><a href="label_dollar.html">label_dollar</a>()</code>, <code><a href="label_number_auto.html">label_number_auto</a>()</code>, <code><a href="label_number_si.html">label_number_si</a>()</code>, <code><a href="label_ordinal.html">label_ordinal</a>()</code>, <code><a href="label_parse.html">label_parse</a>()</code>, <code><a href="label_percent.html">label_percent</a>()</code>, <code><a href="label_scientific.html">label_scientific</a>()</code> </p> <h3>Examples</h3> <pre> demo_continuous(c(0, 1)) demo_continuous(c(0, 1), labels = label_pvalue()) demo_continuous(c(0, 1), labels = label_pvalue(accuracy = 0.1)) demo_continuous(c(0, 1), labels = label_pvalue(add_p = TRUE)) # Or provide your own prefixes prefix <- c("p < ", "p = ", "p > ") demo_continuous(c(0, 1), labels = label_pvalue(prefix = prefix)) </pre> <hr /><div style="text-align: center;">[Package <em>scales</em> version 1.1.1 <a href="00Index.html">Index</a>]</div> </body></html>
