Writing and running R functions

I am having problem in running functions in R. Whenever I want to run them I always get the message that the function/object is not available. though I saved it in the working directory. For it to run, I have to paste it in the R window. Any idea on what I am missing highly appreciated.

So as exposed above, there are several steps to follow. It won't work if one of them is missing :-)

1) Set your source folder

setwd("///.../admin/Documents")

2) Create your function and save it:

fun = function(...){
your function
}

dump("fun", file = "Code_fun.R")

3) Call your function

source("Code_fun.R")

Then you can go ahead

fun(3) = ...

Use the source function to read the file.

If you do this a lot, I recommend the package devtools, or RStudio. Or both.
