Use cat() instead of print:

 > cat(runif(20))
0.7488857 0.7319368 0.2803859 0.3738669 0.5619917 0.3179777 0.2414058 
0.7494183 0.7967387 0.9084999 0.5811184 0.1158764 0.1048582 0.8314966 
0.2892489 0.1403012 0.6296523 0.3318759 0.8797555 0.8332503

There are optional parameters to cat() to insert line breaks (sep="\n"), 
etc.
