title: How to control position of axis label in persp3D in plot3D R package
body: <p>I have managed to create a 3D perspective surface plot using <code>persp3D</code> in <code>plot3D</code>. However when I rotate the plot, the default action is to make the "x2" axis labels "jump" to a point where they can't obscure the data. The effect of this is that an unconventional axis label is created which looks confusing. I would like to be able to keep the conventional axis labeling scheme that one would expect.</p>
  
  <p>Here is the plot, which I have annotated showing the desired position of the x2 axis label, tick marks and tick mark labels. </p>

  <p>Here is my code, which directly writes the jpg file, allowing me to conform accurately to the journal requirements:</p>
  
  <pre><code>jpeg(file="plot500-140-25a.jpg",width=3543,height=3543)
  
  plot3D::persp3D(x,y,z=df3,theta=140, phi=25,xlab="x2",ylab="x1",zlab="Intensity",
  cex.lab=10,cex.axis=5,ticktype="detailed")
  
  dev.off()
  </code></pre>
  
  <p>What can I do to move the axis label, tick marks and tick mark labels to the desired position?</p>
