title: Rotate y-axis label in scatterplot3d (adjust to angle of axis)
body: <p>I use <code>scatterplot3d</code> to plot 3D with R. The orientation of the y-axis label bothers me because it is vertical and not parallel to the y-axis.
  Is there a way to rotate the label and adjust its angle? Unfortunately, I didn't finde anything in the <a href="https://cran.r-project.org/web/packages/scatterplot3d/scatterplot3d.pdf" rel="nofollow noreferrer">documentation</a>.</p>
