  I'm really sorry that you're stuck, but ... waiting until a few days
before an important assignment is due and then depending on the generosity
of unpaid volunteers is a dangerous procedure ...

  I tried to run your code but got an error ("object 'p' not found");
it's very hard to understand what the code is doing, there are lots
of things that look funny/wrong ... in particular, you should look at
the gute() function and think about what it's doing.  Be aware that
functions in R do not work like 'macros', that is, information about
variables that are defined or modified within functions does not 
propagate outside the functions.

  If you post a function that actually works, you are more likely to
get help drawing the graph.

  If your results are in the form of a matrix, persp() is probably
the easiest way to draw the surface. wireframe (in the lattice package)
is an alternative.
