R help - Dec 2007 - plot3d, wireframe, persp help

Hello,
  I am trying to get a surface plot of a data set that looks like the following,
  1  2  5.6
  5  9  2.4
  9  8  9.8
  ... to (60,000 rows down)
   
  From my homework, the persp function only works with evenly spaced data points
with the z data beeing in a matrix.  my data is not in that format.
  the wireframe fxn gives me an error,
  no applicable method for "wireframe"
the plot3d fxn I got working thanks to Scionforbai's help.  However it does
not represent the data like wireframe or persp would.
  Any help would be appreciated.
  thanks

When using the wireframe function you need to create a 2D grid for your two X
variables.  Try the "expand.grid" function on your data, then run the
wireframe on that result
