[R] Reconcile Random Samples

Is there a way to generate identical random samples using R's runif
function and SAS's ranuni function?  I have assigned the same seed
values in both software packages, but the following results show
different results.   Thanks!

R

> set.seed(6)
> random <- runif(10)
> random
 [1] 0.6062683 0.9376420 0.2643521 0.3800939 0.8074834 0.9780757
0.9579337
 [8] 0.7627319 0.5096485 0.0644768

SAS (the log file)
=======
15         data _null_;
16           do i=1 to 10;
17           	random = ranuni(6);
18         	put i= random=;
19         	end;
20         run;

i=1 random=0.1097754189
i=2 random=0.8205322939
i=3 random=0.3989458365
i=4 random=0.5563918723
i=5 random=0.5296154672
