Dear ronggui, I didn't find any attachments, but using the data lines in your message, and assuming that . represents missing data, the following appears to do what you want: as.data.frame(scan("c:/temp/ronggui.txt", list(year=1, apps=1, top25=1, ver500=1, mth500=1, stufac=1, bowl=1, btitle=1, finfour=1, lapps=1, d93=1, avg500=1, cfinfour=1, clapps=1, cstufac=1, cbowl=1, cavg500=1, cbtitle=1, lapps_1=1, school="", ctop25=1, bball=1, cbball=1,), na.strings=".")) See ?scan for details. I hope this helps, John On Sat, 15 Oct 2005 15:57:42 +0800 ronggui <042045003 at fudan.edu.cn> wrote:> the data file has such structure: > > 1992 6245 49 . . 20 > 1 > 0 0 8.739536 0 . . > . > . . . . . > "alabama" > . 0 . > 1993 7677 58 . . 15 > 1 > 0 0 8.945984 1 . 0 > .2064476 > -5 0 . 0 8.739536 > "alabama" > 9 0 0 > 1992 13327 57 36 58 16 > 0 > 0 0 9.497547 0 47 . > . > . . . 0 . > "arizona" > . 0 . > 1993 19860 57 36 58 16 > 1 > 1 0 9.896463 1 47 0 > .3989162 > 0 1 0 1 9.497547 > "arizona" > 0 1 1 > 1992 10422 37 28 58 20 > 0 > 0 0 9.251675 0 43 . > . > . . . -1 .
