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

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. Duncan Murdoch> P.S. I've tried this on versions 2.11 and 2.9 and the results are the same. > >
What I was expecting was for the second dump was: foo <- structure(c(1,2,3,4,5,6), .Dim = c(2L, 3L)) That is, I was expecting dump to expand the 1:6 and 2:3 into the actual vectors. -- View this message in context: http://r.789695.n4.nabble.com/dump-not-evaluating-promises-tp2075859p2076059.html Sent from the R help mailing list archive at Nabble.com.
