Hi, I'm embedding R in an application under Debian Linux. I need to plot some graphicals using R, but they don't redraw. My program uses qt graphical library. I read in "Embedding R in Other Applications" that "... R should be able to export the file descriptors on witch it is waiting for events and also the callbacks...," but this document don't tell how to export it. I have to control the R event loop in my program or is there an R function that I can call to do this? Is there any documentation about it? Best regards, Pedro Andrade
