Question

Take a basic function

fun<-function(){
x<-c(1,2,3,4,5)
y<-c(1,2,3,4,5)

t<-x+y
return(t)

}

After I have run the function, is there a way I can access any of the variables created within the function. Either by specifying the variable- something like this:

fun$y

or

fun$t

or is there some way of asking R to save the variable within the function for use during my current R session (I’m not looking to save it permanently). AKA something along the lines of:

fun<-function(){
x<-c(1,2,3,4,5)
y<-c(1,2,3,4,5)

t<-x+y
Y<-save y for latter use
T<-save T for latter use
return(t)

}

Thanks!

Answer 1

You can’t use a variable outside of its scope.

What you can do is use a list to return multiple values from your function.

Here’s a good example.
