Thanks to all of you.
That's what I want.
Best wishes,

Try
tapply(prevRND.dat$Z, list(X=prevRND.dat$X, Y=prevRND.dat$Y), mean)

How about:

xtabs(Z ~ X + Y, data = prevRND.dat)
 

  Y
X   A        B        C       
 A 0.950933 0.143600 0.956133
 B 0.000533 0.986467 0.032066
 C 0.005333 0.000000 0.009266

HTH,
