[R] Example in R-intro "Vector arithmetic" is wrong

[Holger Schurig]

In Chapter "Vector arithmetic":

------------------
constant is simply repeated.  So with the above assignments the command

   > v <- 2*x + y + 1
------------------

yields a

> v <- 2*x + y + 1
Warning message:
longer object length
        is not a multiple of shorter object length in: 2 * x + y

This is because

> x
[1] 10.4  5.6  3.1  6.4 21.7
> y
 [1] 10.4  5.6  3.1  6.4 21.7  0.0 10.4  5.6  3.1  6.4 21.7

Because one example was "y <- c(x, 0, x).
