[R] unexpected subset select results?

[ivo welch]

quizz---what does this produce?

   d=data.frame( a=1:1000, b=2001:3000, z= 5001:6000 )
   attach(d); c <- (a+b)>25; detach(d)
   d= subset(d, TRUE, select=c( a, b, c ))

yes, I know I have made a mistake, in that the code does not do what I
presumably would have wanted.  it does seem like unexpected behavior,
though, without an error.  there probably is some reason why this does
not ring an alarm bell...
