    copied!<p>Consider the following minimal example:</p> <pre><code>tab = structure(c(187, 189, 205, 167, 273, 275, 295, 231, 385, 575, 409, 363, 899, 707, 751, 667, 2007, 1953, 2101, 2531, 1043, 1023, 1071, 971, 385, 575, 409, 363, 181, 241, 157, 163, 123, 163, 133, 131), .Dim = c(4L, 9L), .Dimnames = list(NULL, c("-4", "-3", "-2", "-1", "0", "1", "2", "3", "4"))) </code></pre> <p>The matrix <code>tab</code> contains counts of a 9-Point Likert Scale.</p> <p>A basic plot is easy to produce:</p> <pre><code> likert(tab, auto.key=list(between=0.5, between.columns=1), main="Attitudes", BrewerPaletteName="RdBu",as.percent=TRUE, rightAxisLabels=NULL, rightAxis=NULL, ylab.right="") </code></pre> <p>And it looks nice. Now, the problems:</p> <ul> <li>I would like to control the increments of the percentage axis. In some cases, with other counts, it only shows 50%. I want to enforce 10% increments</li> <li>I want to add the % count as a label. Most importantly for the 0-category. Like in Excel, where you right click and say "add data labels". There must be something similar.</li> </ul> <p>I also considered ggplot, however, it does not support the diverging plots. Plus labeling is also quite messy, especially for tikz export.</p> <p><strong>EDIT</strong> I have tried using panel.text. However, I still don't get the numbers alined correctly.</p> <pre><code>#does not work right! trellis.focus("toplevel") for(pp in 1:nrow(tab)){ panel.text(0.5, (pp/nrow(tab))*0.84+0.16, tab[pp,5], cex = 1, font = 2) } trellis.unfocus() </code></pre> <p>How can I find the right positions within each bar?</p>
