ifelse is vectorized but there is no way you could know what's
happening with that command
because you have rnorm(1) for both conditions. I think you mean to have
something different in one of them ?
Whewn I run your code in my R session, I get 10 values for y1, so there
isn't anything wrong
You can indeed compile and run R directly through the unix layer in Mac
OS (or at least you could about 2 years ago, which was the last time I
tried).

But you got only two (eventually one) distinct values, right? Look at
the code for 'ifelse': yes and no are only called once each, then
recycled to desired length.
I guess you want something like

y - rnorm(10)
z - rnorm(10)
y1 - ifelse(x 0, y, z)

I find it more puzzling why
I think you can find your answer if you study this part of the
documentation for ifelse:
Details:
If yes or no are too short, their elements are recycled. yes will be
evaluated if and only if any element of test is true, and analogously
for no.
Also, consider this call:
ifelse(1:12 5, 1:3,
...ifelse, a function of three **vector** arguments
Yes !!
I misunderstood the functioning of ifelse.
