title: 3d (interactive) plot and regression line in R
body: <p>I have x,y,z data that I would like to plot in R together with a regression line I fitted to data. Prefereably interactive plot, but a static would be fine as well.</p>
  
  <p>I am currently using the 'car' package to generate an interactive plot. How can I add the regression line?</p>
  
  <pre><code>    library(car)
      data(iris)
      f &lt;- lm(iris$Sepal.Length ~ iris$Sepal.Width + iris$Petal.Length)
      scatter3d(x=iris$Sepal.Length, y=iris$Sepal.Width, z=iris$Petal.Length, point.col = "blue", surface=FALSE)
  </code></pre>
  
  <p>Or any other package that could make such a plot in R?</p>
  
  <p>Any help appreciated.</p>
