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

loess() is a 'local' fitting procedure, which means that it fits a different regression at each prediction point. (In principle, for there are computational short cuts: see ?loess.control.) Since each fit is only used for a single prediction, its coeffiicients are not of interest and not made
