[R] stop further sourcing of an R file

[Gabor Grothendieck]

This will source lines up but not including the first line with
exit in it:

z <- readLines("myfile.r")
z <- textConnection(z[seq(grep("exit",z)[[1]]-1)])
source(z)
close(z)

Hello,
Thanks to people who responded to previous mail!

Is there a way in which we can stop further sourcing
of an R file? i.e., i am sourcing an R file and keep
an equivalent of 'exit' in it and run the code till that point?

Thanks again
Regards
Ramakrishna
