[R] read.table

[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
