What is it that you want to do? The 'scan' statement give you a list
of length 7000 with 19 entries each. Do you want to create a matrix
that has 7000 rows by 19 columns? If so, then you just have to take
the output of the 'scan' and do:
x.matrix <- do.call('rbind', x) # gives 7000 x 19 matrix.
So I am still not sure exactly what your input is and what you want to
do with it.
