R help - Dec 2010 - R2WinBugs data import error

For some purpose, I  need to transfer a NAs array to WinBugs through
R2WinBugs, But I constantly got an error message:"'type' must be
"real" for
this format". Here is my data to transfer:

x = matrix(data=NA,nrow=3,ncol=3)
x =  as.array(x)
data <- list ("x")

if I add a line to above setting, then I can pass R2WinBugs:

x[1,1] = 0

If I manually input the NA array to WinBugs, I could get it running. So my
original data set has no problem with WinBugs.

str(x)
It is of mode "logical".

Try instead:
x = matrix(vector(mode="numeric",0) ,nrow=3,ncol=3)

Why are you making a list with a single character element? If you need  
to pass the matricx you just created in a list then try (and don't use  
"data" as the name :

dat <- list(x)
