  "Description": "Methods for fast access to large ASCII files.  Currently\nthe following file formats are supported: comma separated\nformat (CSV) and fixed width format. It is assumed that the\nfiles are too large to fit into memory, although the package\ncan also be used to efficiently access files that do fit into\nmemory. Methods are provided to access and process files\nblockwise. Furthermore, an opened file can be accessed as one\nwould an ordinary data.frame. The LaF vignette gives an\noverview of the functionality provided.",
