[R] Make a table

[Muhammad Subianto]

Dear useR,
I have a dataset like this below,
> prevRND.dat   <- read.table("C:\\workdir\\prevRND.txt",
+                           header=FALSE,  # No header.
+                           col.names = c("X","Y","Z"),
+                           sep = ",")
> prevRND.dat
  X Y        Z
1 A A 0.950933
2 A B 0.143600
3 A C 0.956133
4 B A 0.000533
5 B B 0.986467
6 B C 0.032066
7 C A 0.005333
8 C B 0.000000
9 C C 0.009266
How can I make that data above as table,
                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
I cannot use table() or ftable() functions because the 3rd column (Z) is 
probability. Are there any function to make a table as I want?

Kind regards,
Muhammad Subianto
