To reproduce the SAS results in R, you need to specify the ks.test something
like:
ks.test(y[x==1], y[x==0],alternative = c("two.sided"),exact = NULL)
I say something "like", because I don't know what the binary values for x are,
so I just used 1 and 0. If this doesn't help, then you need to provide some
data and your actual results so that you have an actual reproducible example
(see the posting guide).
Hope this is helpful,
