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)
str(x) It is of mode "logical". Try instead: x = matrix(vector(mode="numeric",0) ,nrow=3,ncol=3)
x = as.array(x)
data <- list ("x")
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)
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. --
