[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?

Re: [R] Running code sequentially from separate scripts (but not functions)
You say you are aware that you can source them from a common script, yet you don't seem satisfied with that. Perhaps you could be more specific about why that solution is not satisfactory? One thing you said could indicate a misunderstanding... you do not have to wrap the code in functions before you source the files. --- Jeff Newmiller The . . Go Live...

Re: [R] Running code sequentially from separate scripts (but not functions)
If you are just wanting to run them once, you can just do: source(code1.r) source(code2.r) source(code3.r) or place the file names in a vector, say 'filenames' and: sapply(filenames, source) If you want to use them multiple times, try: run1 - parse(code1.r) run2 - parse(code2.r) run3 - parse(code3.r) # Use this to run anytime eval(run1) eval(run2) eval(run3) -- Jonathan P.

Re: [R] Running code sequentially from separate scripts (but not functions)
Thanks a lot, everyone! Honestly - I just did not know one could source everything and not just functions. What you wrote is simple, but pretty eye-opening for me (and extremely helpful)!

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) ...
