foreign does not read in data in sparse arff format unfortunately :-( Even if I convert my data into non-sparse format, it will take a really long time to load in. Is there a way to read in data from external file (ARFF, CSV or whatever) directly into sparse data structure like Matrix or sparsem without having to first read it into a data frame?
