I am writing a kind of long program in R and I have some variables which I want to be globals. Where should I save them? I was thinking to create a function wich initialize all the global variables and then whenever I need them, I call this function.
In most cases, you would write a function that would
return an object of class list, the components of
which would be the values you want to use later.
For example
myfun <- function([stuff]){
[stuff]
return(list = (var1 = val1, var2 = val2)
}
and your call would be
glob <- myfun([stuff])
and you would access val1 with
glob$var1
What if I create a file glob.R with
var1<-val1
var2<-val2
.....
etc.
How do I include this file in my other files/function . Is there in R
some kind of include("glob.R") or something?
thank you,
Johan
Use
source("glob.R")
