title: 3D surface plot in R
body: <p>I'm trying to create a 3D plot in R-Project. I know there was a question like this before but I couldn't solve my problems with the answers there.</p>
  
  <p>What I have is:</p>
  
  <pre><code>Vdot_L = c(0,1,2,3,4,5,6,7,8,9,10)
  Qdot_verd = c(2000,2100,2200,2300,2400,2500,2600,2700,2800,2900,3000) 
  zeta_ex = 0.4
  T_U = 293.15 #K
  T_verd = 273.15 #K
  T_cond=Vdot_L*2+T_U
  epsilon_k = zeta_ex * T_verd/(T_cond - T_verd)
  Pfun &lt;- function(a,b) {a/b}
  P    &lt;- outer(Qdot_verd, epsilon_k, FUN="Pfun")
  </code></pre>
  
  <p>What I'd like to create is a colored surface plot with <code>Vdot_L</code> on the x-Axis, <code>Qdot_verd</code> on the y-Axis and <code>P</code> on the z-Axis. I'm thanful for every help.</p>
