LaF: Fast access to large ASCII files
The LaF package provides 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.
