[R] Random numbers from noncentral t-distribution

Hi there:    

  I'd thought these two versions of noncentral t-distribution are essentially the same:
> qqplot(rt(1000,df=20,ncp=3),qt(runif(1000),df=20,ncp=3))

  But, the scales of the x-axis and the y-axis are quite different according to the QQ-plot.    

  Did I make any mistakes somewhere?        

  Thanks,
  Long
