[R] Correlated variables

[Art U]

Hi,

I'm trying to create binary variable which distribution conditioned on
other variables. That is what I did,

x1=rnorm(n,0,1);
x2=rnorm(n,0,1);
x3=rnorm(n,0,1);
if(x1+x2-x3>0.25){
  t=rbinom(1, 1, prob=0.25)
}else{
  t=rbinom(1, 1, prob=0.5)
}

But I always get this the warning:

Warning message:In if (x1 + x2 - x3 > 0.5) { :
  the condition has length > 1 and only the first element will be used


Can I do this without using function "for"?

Thank you in advance.
Ariel
