title: Remove axis labels in R conditional density plot
body: <p>I could not manage to remove the y axis labels from a conditional density plot (cdplot{graphics}) in order to rotate them horizontally later; <code>axes = FALSE</code> seems not to work. Any idea?
  <strong>Thanks!</strong></p>
  
  <p>Using the example data from R documentation:</p>
  
  <pre><code>fail &lt;- factor(c(2, 2, 2, 2, 1, 1, 1, 1, 1, 1, 2, 1, 2, 1, 1, 1, 1, 2, 1, 1, 1, 1, 1),
                 levels = 1:2, labels = c("no", "yes"))
  temperature &lt;- c(53, 57, 58, 63, 66, 67, 67, 67, 68, 69, 70, 70, 70, 70, 72, 73, 75, 75, 76, 76, 78, 79, 81)
  cdplot(fail ~ temperature, axes = FALSE)

  1: In density.default(x, bw = bw, n = n, ...) :

  2: In density.default(x[y %in% levels(y)[seq_len(i)]], bw = dx$bw,  :
