Hello,
Also, unlike what the op says, if statements are functions, explaining the
behavior he got.
I'm not sure that is correct. The help page says if() is a control-construct. I think the
function is actually "{"
{rnorm(10); rpois(10, 3)}
[1] 5 3 5 5 7 3 4 4 0 5
See
?Paren
It has nothing to do either with if() or Paren. It is the ***user's***
function that is suppressing the output. Consider:
foo <- function(){
x <- 17
x
y <- 42
y
}
If you type foo() you get
[1] 42
which is the *value returned by the function. The value of the "x"
statement inside foo() is made invisible (and would have to be enclosed
by print() to be made visible).
cheers,
Rolf
