Requiring the user to actually do that is a disaster regarding usability. In SageMathCloud I just make it automatic. E.g.,doing this just works: %r cars <- c(1, 3, 6, 4, 9) plot(cars, type="o", col="blue") title(main="Autos", col.main="red", font.main=4) See: https://cloud.sagemath.com/projects/4a5f0542-5873-4eed-a85c-a18c706e8bcd/files/support/2015-10-26-092322-r-plot.sagews I don't think I've done the analogous thing for Octave yet, but should. The way it works is by making %r *slower* when used interactively, by having it check to see if a new graphic was created each time it runs, and if so, displaying it. The codes all open source. Sage Cell server should be changed to do the same, in my opinion. However, leave the sage library's r.eval itself alone, since doing the above would slow it down.
