Currently there is no support for including table values literally
inline in tangled R code. While some languages (e.g., the lisps) do
include table values literally, R is not one of those. You could
customize (read rewrite) the `org-babel-R-assign-elisp' function to use
literal R tables instead of importing values from an external file.
Alternately, if not too many values need to be included into the code,
you may want to simply assign individual cells of the table as scalars
in your R code.
Hope this helps, sorry no pre-built solution exists
