[R] how to use a script file for all the codes?

[Gabor Grothendieck]

You can do this:

f <- function(x)x
fix(f)
# you are now put into an editor and can change the function
# when you save the file you will be taken back to R with the new version of f

Alternately, you can ease the use of the source style of operating
by hitting up-arrow a few times in the R console to get your last 
source command so its just a matter of upwarrowing and pressing Enter.

One other thing to note is that there are a number of editors that support
R syntax highlighting including ESS and gvim and that can ease development
too.
