I don't know how to do this in the way you describe.
Easy alternatives include:
- putting the part of the script that is to be executed
conditionally into a separate file, and then source it or not based
on some condition.
- simply wrapping the different parts of the script in if, then, else blocks.

Hi,
I am using a script to initialize variables in the global workspace.
Based on some condition, I would like to stop evaluation of a script
sourced on the command-line, without issuing an error.
My current solution is the following hack that uses a repeat { }
statement
----------- init.R -----------
#hack to enable setting of breakpoint
repeat {
...
if (condition) {
break;
}
...
# remember to break !!
break;
} #end repeat
EOF
Thanks,
- Stu
