Exercise

Compare read.delim() and read.delim.raw()

When processing a sequence of contiguous chunks of data on a hard drive, iotools can turn a raw object into a data.frame or matrix while - at the same time - retrieving the next chunk of data. These optimizations allow iotools to quickly process very large files.
