This question is related to FAQ 7.16, which you should look up.
In general, whenever you just type a variable or function directly at the
command line, R prints the result for you. Inside code blocks of any kind,
it does not do that, so you need to use the print function yourself.

Hello,
I have a block of code that has two head calls at the end, but only the second
is shown on screen. If I manually execute the statement which is not showing,
it works. I thought that if statements are not functions. It is behaving as one.
if(1 < 2)
+ {
+ x<-rnorm(100)
+ y <- rpois(10, 5)
+ head(x)
+ head(y)
+ }
