My understanding is that this is normal R output and the plot is created. You just don't see it because it is in a wrong directory. > > Andrey: > Do you think it is possible to use the sage_salvus.py code in Sage Cell? > Yes, I am looking into it. Definitely will not start working today, but perhaps in a week or so I can fix it so that you get a link to "general files" created from R and plots are displayed automatically. > One more question, is there some log file for sage cell which I dig into? > See https://github.com/sagemath/sagecell/blob/master/log.py which works in default configuration (I guess messages will just go to your syslog), as well as https://github.com/sagemath/sagecell/blob/master/contrib/vm/container_manager.py#L171 and https://github.com/sagemath/sagecell/blob/master/contrib/vm/compute_node/etc/rsyslog.d/sagecell.conf which are used "in production": there are detailed logs inside of each container and a summary one on the host. I doubt these logs are very useful with debugging R (or Sage) issues since from the point of view of the cell server "everything works", you just don't have access to results. > > -Benedikt > > On Monday, October 26, 2015 at 12:13:08 PM UTC, Benedikt Magnússon wrote: >> >> Hi >> >> I wish to be able to plot in Octave/R inside a sagecell. >> Therefore, I just set up a sagecell server using the instructions here >> https://github.com/sagemath/sagecell >> >> >> I compiled my own sagecell server because when you use >> https://sagecell.sagemath.org >> you get the following when trying to plot in R: >> "Error in png() : X11 is not available" >> >> https://sagecell.sagemath.org/?z=eJwryMkv0UjWMNRRMNZRMNNRMNFRsNTUBABEDAT8&lang=r >> and in Octave you only get a Ascii plot >> https://sagecell.sagemath.org/?z=eJwryMkv0Yg21DGM1QQAFu8DVw==&lang=octave >> >> Using my own server plotting in R gives me nothing >> (not even "Error in png() : X11 is not available") >> and Octave still gives me only Ascii. >> >> I have two related questions: >> 1.
