[R] Reading SAS data into R

[Shubha Vishwanath Karanth]

Oh!...Got that...A member in the RD library of SAS can contain only 8 characters in its filename. Since the variables 'tsubset1', 'tsubset2',....'tsubset9' had exactly 8 letters in the name, those files read properly.... and then onwards, since the number of letters/characters exceeded 8, those were not read!
