[R] Running code sequentially from separate scripts (but not functions)

[rex.dwyer at syngenta.com]

You don't need to write functions to "source" files:

source("code1.R")
source("code2.R")
source("code3.R")

When you source a file with a bunch of function definitions, the definitions are just assignment statements:

f <- function (x)...
g <- function (x,y,z) ...

Did you think you would break your computer if you just tried this to see if it worked?  :)

Subject: [R] Running code sequentially from separate scripts (but not functions)

Hello!

I am wondering if it's possible to run - in sequence - code that is
stored in several R scripts.
For example:

Script in the file "code1.r" contains the code:
a = 3; b = 5; c = a + b

Script in the file "code2.r" contains the code:
d = 10; e = d - c

Script in the file "code3.r" contains the code:
result=e/a

I understand that I could write those 3 scripts as 3 functions and
source them from another script.
But maybe there is a way of having them run one by one as such?

Thanks a lot!
