%description
Methods for fast access to large ASCII files.  Currently the following
file formats are supported: comma separated format (CSV) and fixed width
format. It is assumed that the files are too large to fit into memory,
although the package can also be used to efficiently access files that do
fit into memory. Methods are provided to access and process files
blockwise. Furthermore, an opened file can be accessed as one would an
ordinary data.frame. The LaF vignette gives an overview of the
functionality provided.
