q() will terminate the entire R session.
I suspect what Ramakrishna wants is to set a break-point
in a source file, so as to just read in part of it, and
then continue in the R session with other things.
Though not what it's intended for, 'break' will do the job.
E.g. if test.R contains
x<-pi*0.01*(0:200);
plot(x,sin(x))
break
plot(x,cos(x))
then after
source("test.R")
R will plot the sine curve, but not the cosine curve, exiting
at 'break' with the message
No loop to break from, jumping to top level
and the R session will still be intact, including any variables
created in the script.
