Here is the data file:
x y z
1 1 1
1 2 2
2 1 NaN
2 2 4

>data<-read.table("~/junk.dat",header=TRUE)

> data
  x y   z
1 1 1   1
2 1 2   2
3 2 1 NaN
4 2 2   4

> matrix(data$z,length(y),length(x)) 
     [,1] [,2]
[1,]    1    4
[2,]    2    3

This is not the correct matrix.  It seems that NaNs screw up matrix().
