[R] Error using return() function inside for loop and if statement

Dear all, I get an error using the return function. The following is a simpler version. for (j in 1:10) { samples = 5*j return(samples) } Error: no function to return from, jumping to top level Similar warning happens with if statement. Why do I get an error? print() works fine. I

Re: [R] Error using return() function inside for loop and if statement

The error message should make it pretty clear -- you aren't inside a function so you can't return() a value which is, by definition, what functions (and only functions) do.** Not sure there's a great reference for this though beyond the error message Incidentally, what are you trying to do
