I'm using the dump command to pass data to WinBUGS/OpenBUGS/JAGS and have run into a problem.Here is some R-code: foo <- array(1:6, dim=c(2,3)) dump('foo', file='dumpdata.R') dump('foo', file='dumpdata.R', append=TRUE, evaluate=TRUE) foo2 <- array(c(2,3,5,7,9,7,5,3), dim=c(2,4)) dump('foo2', file='dumpdata.R', append=TRUE) And here is the file dumpdata.R: foo <- structure(1:6, .Dim = 2:3) foo <- structure(1:6, .Dim = 2:3) foo2 <- structure(c(2, 3, 5, 7, 9, 7, 5, 3), .Dim = c(2L, 4L)) Looking at the help page, the second dump of foo should look like the dumpof foo2 because the evaluate=TRUE flag tells it to evaluate the promises. Unfortunately dump's control parameter didn't offer any solution, either. Am I missing anything?
I don't get it. Why would the second dump not show the values 1:6? How would it know about the vector or the new dimension that you put into foo2?
I think you need to be more explicit about what output you were expecting, and why.

P.S. I've tried this on versions 2.11 and 2.9 and the results are the same.
