[R] trouble in (scan -- read.table)

[hkimscil]

Hello all -
I must be wrong in using commands...  

The below is my data (test.data). Its size is 10 X 15.
1 1 1 1 1 1 0 1 1 1 1 1 0 1 0
1 1 1 0 0 1 0 0 0 1 0 0 1 1 1
1 1 1 0 0 1 0 1 0 0 0 1 1 1 1
0 0 0 0 1 1 0 0 0 1 1 0 0 1 1
1 1 1 1 0 1 0 1 0 1 0 0 0 1 1
0 1 0 0 0 1 0 0 0 1 1 0 1 0 0
1 1 0 1 0 1 1 1 0 0 1 0 1 0 0
1 1 0 1 0 1 1 1 0 1 0 1 1 0 0
0 1 1 1 1 1 1 0 1 1 0 1 1 0 0
1 1 0 0 0 1 0 0 1 0 1 1 1 0 0

I am importing the data into a matrix test1, using scan.
> test1<-matrix(scan("test.data"),nrow=10,ncol=15)

Then, I do the same thing with read.table
> test2<-as.matrix(read.table("test.data"))

Now, test1 and test2 are different (test2 is the correct one).

test1:
1 1 1 1 0 1 1 0 1 1 1 1 0 0 1
1 1 0 1 1 0 1 0 0 1 0 1 1 1 0
1 0 0 1 1 0 1 0 0 0 1 1 1 1 0
1 1 0 0 1 0 1 1 0 1 0 0 1 0 1
1 0 1 0 1 1 0 1 1 0 0 1 1 0 0
1 1 0 1 0 1 1 0 1 1 1 0 1 1 1
0 1 0 0 0 0 0 1 0 1 1 1 1 1 1
1 1 1 1 0 0 1 0 1 1 0 1 0 0 1
1 0 1 0 0 1 0 0 0 0 1 0 1 0 0
1 0 1 0 1 1 1 0 0 0 0 0 1 0 0

test2
