Not that I am aware of. However, the only exit codes that I am aware that
R itself produces are via R_CleanUp, and I can see that called with
0, 1 and 2.
0 is a normal exit
1 is an error exit in non-interactive mode
2 is `suicide', a catastrophic error (or termination by SIGUSR1)
I think error codes like 137 come from your C run-time system.
