read.table 2005-07-13 - By Weiwei Shi
add:
I used
trn<-matrix(scan('train1.dat', sep='|', na.string='.'), nrow=273529, ncol=195)
it is done.
so it seems that I just have no patience to wait for half an hour :)
but i still have that question:
is there a way to track the process if it takes too long. Could we
stop in the middle to see at which line it "hesitates" to move on?
regards,
weiwei
