this is from memory, and may not be entirely correct, but roughly it's this: If R notices it is not connected to a PTY, it goes into scripting/batch mode (i.e. interactive () == FALSE). This means, it will exit on any error. As far as I recall, this behavior cannot be changed, or at least not easily so. A way to work around this is to embed R: http://stat.ethz.ch/R-manual/R-devel/doc/manual/R-exts.html#Linking-GUIs-and-other-front_002dends-to-R then set R_ConsoleFile = NULL, and override ptr_R_WriteConsole (Linux) or Rd->WriteConsole to point to your own function to handle output. Several slightly different solutions are possible, but the key is to avoid having R go into batch mode.
