title: How to vertically justify text data labels in R barplot along the y-axis?
body: <p>The following code provides a simple illustration of the issue:</p>
  <pre><code>testX = c(9, 10, 15, 100, 8)
  barX &lt;- barplot(testX, ylim=c(0, max(testX)))
  text(x=barX, y=5, labels=round(testX), xpd=TRUE, srt=90)
  barX
  </code></pre>
  <p>I would like the vertical text data labels to be left justified (along the y-axis... &quot;bottom justified&quot; if you will), rather than the default center justification seen here; (in the final two columns, see how the &quot;100&quot; starts lower than the &quot;8&quot;.... in a larger plot with more columns, this becomes very unsightly):
