You need to answer some questions:

1. Does the data of Z is evaluated in a grid of X and Y?

If yes: Then you can use the function mesh (or surf) to plot the data
after you have reshaped it using reshape.
If no: You can make a traingulation of the X,Y points (unsing
deluanay) and then plot using the functions in themsh and fpl package.
