Replying to Posts Within Same Thread
Hi,
When I reply to a post, it generally appears as a separate thread,
rather than branching off the original post.
Anyone know what I'm doing wrong?
Noting I am currently receiving a couple of the lists in digest form.

Reading sas7bdat files into R
Hi All,
I am trying to import a .sas7bdat file into R.
I tried using Hmisc package's sasxport.get() function.

I am not familiar with SAS transfer format.
