Both times the *R* session buffer gave identical output, as follows: > x <- 1:5 > y <- data.frame(A=x, B=round(sin(x/3.3),3)) > > y A B 1 1 0.298 2 2 0.570 3 3 0.789 4 4 0.936 5 5 0.998 > > I also took a look at the *Messages* buffer in emacs. In the first (failed) export It left the message executing R code block... Starting evaluation... Finished evaluation result is (nil hline) In the second (successful) export the equivalent lines were executing R code block... Starting evaluation... Finished evaluation result is (("A" "B") hline (1 0.298) (2 0.57) (3 0.789) (4 0.936) (5 0.998)) Erik Iverson wrote: > What does your *R* session buffer look like > when this does and does not work?
