Hard to tell what exactly's going on from here, but Python itself is
quite happy to create and manipulate strings much larger than 65k --
its maximum is somewhere in the gigabytes range, if that. (That's a
suspicious number, though -- perhaps some of your widgetry somewhere
has a 2**16 limit?)

robjects.r("foo") doesn't print anything itself. (Unless 'foo' calls
the print() function.) Try robjects.r("print(foo)") or
robjects.r["print"](robjects.r("foo")).
