I have a text file of R commands. Some times I only want to run a few lines
of the R commands in an existing R session and wonder whether there is a
simple way to do this.
To run a few lines in a new session of R, I could use sed to pick up the
lines from the file and pipe them into R.
source() does not allow me to specify which lines to be included/excluded.
Is there any function that is similar to source() but allows me to specify
lines included/excluded?
Paul.
