If R is killed with "kill -USR1 pid" it will terminate and save its workspace overwriting any exiting .RData-file even if R has been started with the --no-save option. Preferably R should always respect the --no-save option and this should thus be used to determine if the workspace is saved when receiving the USR1 signal.
The following change will adopt this behavior (based on R-2.12.2 source). $RHOME/src/main/errors.c, line 147 - R_CleanUp(SA_SAVE, 2, 1); /* quit, save, .Last, status=2 */ + R_CleanUp(SA_DEFAULT, 2, 1); /* quit, save, .Last, status=2 */ $RHOME/src/main/errors.c, line 197 - R_CleanUp(SA_NOSAVE, 0, 0); + R_CleanUp(SA_DEFAULT, 0, 0); The documentation in $RHOME/src/library/base/man/unix/Signals.Rd should also be updated accordingly. To my knowledge it is not possible to send a USR1/USR2 signal on windows so this issue is only relevant on POSIX compliant systems. Best regards, Stig B.
