Two functions give the same results - which one is correct/best practice?

Both of these results are giving me the same answer/expected result. Is one method better than the other? Why doesn't method 1 require an else statement?

Method 1:

thisFunction <- function (n,p) {
    if(n >= p) 
        return(n + p)
    if(n < p)
        return(n * p)
}

Method 2:

thisFunction <- function (n,p) 
{
    if (n >= p) 
    {
        return(n+p)
    }
    else 
    {
        return(n*p)
    }
}
