Could this be a problem with whatever tool (I'm assuming ESS) you are
using to maintain the R session and generate the R file?

Perhaps babel needs to modify the R code used to create the file (held
in the `org-babel-R-write-object-command' variable).  Could you take a
shot at providing another version of this variable?  I don't really use
R myself.

Thanks,
