I get what Jeremie reports (but he has a blank line inserted after the first
line, IIUC)
This is with:
GNU Emacs 26.1
Org 9.2.3
ess-version: 18.10.3
R version 3.6.0 (2019-04-26)
I believe this is new-ish behavior. I see some older files without the extra
line. Also, I think there are recent changes in ESS that pertain to comint
sessions.
FWIW, here is a clip from my session:
--8<---------------cut here---------------start------------->8---

a <-sprintf("%.2f",12.234324)
cat(a,sep="\n")

If Nick sees something different maybe a change in ESS is the culprit.
Not sure what the right path forward is ob-R.el, but as a workaround the OP can
use a :post header arg to strip the offending line.
HTH,
