So, the representation of things like very large numbers depends on how that was done in emacs-lisp, independent of the source language conventions. In this case, I suspect the number was written with a formatting string and ‘%g’ which uses scientific notation if that is a shorter representation. > But if the header :results output, the result was expected. > ,---- > | > | #+BEGIN_SRC R :results output > | df <- data.frame(c1="123456789123456789",c2=2) > | df > | #+END_SRC > | > | #+RESULTS: > | : c1 c2 > | : 1 123456789123456789 2 > `---- > With :results output the results aren't translated into emacs-lisp. Instead, the output from the source language is collected and displayed in the buffer. Thus, the output conventions of the source language are respected. hth, Tom -- Thomas S.
