title: Plotting dates in 3D plots R
body: <p>I am trying to plot date, x and y in a 3D plot in R. (Using RStudio 0.99.903), R (3.3.2), scatterplot3d(0.3-40), rgl(0.98.1)</p>
  
  <pre><code>dates = c("2016-11-10","2016-11-20","2016-12-01","2016-12-15","2016-12-30")
  
  x = rnorm(5,0,1)
  
  y = rnorm(5,1,2)
  
  A = data.frame(dates, x, y)
  
  A$dates = as.Date(A$dates,"%yyyy-%mm-%dd")
  
  library(scatterplot3d)
  
  with(data=A, scatterplot3d(x=x,y=y,z=dates))
  
  This plots the dates as integers
  
  I also tried the rgl package, but get the same result.
  
  library(rgl)
  
  plot3d(x=A$x,y=A$y,z=A$dates)
