Dear list, we would like to add support to interrupt R to StatET (the Eclipse plug-in for R) on any platform. StatET uses JRI of rJava to embed R into the Java application. But JRI currently supports canceling of R commands only on Windows. So we are looking for a way to add support for other platforms too. It is not a specific problem of StatET but of all JRI based GUIs, e.g. of JGR. On Windows, JRI sets the flag "UserBreak" to interrupt R. If I understand the extension manual and postings on this list correctly, there is no similar easy way on Linux? The second way to interrupt R supported also on Linux seems to be sending signals (SIGINT) to the R process. This is tricky in mixed environment (java + native code), but perhaps it works. The rough idea is, to enabled reduced usage of signals by Java (argument -Xrs) and then let R install its signal handlers. I would like to know if somebody already tried that or the like (with success or with which problems)? Best, Stephan
