Another message about the R to TeXmacs interface. 1. Graphics The TeXmacs interface allows the user to directly insert graphics into the session.
Since I am not very familiar with programming for R, I implemented the interaction with graphics in a very primitive way. It was two modes of working: with X11, and without (for example when working remotely through ssh without forwarding X11). In both cases the user has to invoke a command, v(), in order to insert the current graph into the buffer at the current place. With X11, the way it works is that when v() is invoked I call recordPlot(), then open a postscript file, then replayPlot(), and then close the postscript file and insert it into the session. Without X11, I open a postscript file ahead of time, then when v() is called, I close it, and insert it into the session, and then open a new postscript file. Obviously quite primitive.I think ideally would be if everything was transparent to the user - the user does a plot, and the plot is inserted into the buffer right away, and later, updates to the same plot update the original plot where it is. But to be able to do that I need to be able to generate the postscript file of the current plot, and be notified somehow whenever the plot changes. Is all that possible? Is there a better way to implement this all? 2. Libraries A remotely related question is this: the interface with TeXmacs generates menus that depend on the currently loaded libraries. I'd like to be able to update the menus whenever a new library is loaded. Is there a possibility to have a function called whenever this happens? Or would it be advisable to change the global 'library' function? -- View this message in context: http://r.789695.n4.nabble.com/what-is-the-best-way-for-an-external-interface-to-interact-with-graphics-libraries-tp2530208p2530208.html Sent from the R devel mailing list archive at Nabble.com. ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
