Instead, use the better 'fst'\npackage, see http://www.fstpackage.org/, which now includes faster and better\nin-memory compression methods `fst::compress_fst` and `fst::decompress_fst`\ncovered here, as well as several file-based compression options.\n\nNote that neither this package nor the fst package include proper streaming\noptions to arbitrary connections...something someone should add to fst!\n\nOctober, 2018: there were some severe internal lz4 bugs that apparently also\naffect the fst package. I re-activated this repository to update lz4 for those\nwho are still using it, and will file bug reports against fst...\n\nHowever, one potential advantage of this package is default single-threaded\noperation (when used in process-parallel settings)--although that can be\novercome with a function in the fst package, and compatability with the\ncommand line lz4 file format, see for instance the example in the help page for\n`?lzDecompress`.\n\n\n# lz4 Data Compression/Decompression Functions \n\n## Installation\n\nEasiest to install with the `devtools` package:\n```r\ndevtools::install_github(\"bwlewis/lz4\")\n\nlibrary(lz4)\n?lzCompress\n```\n\n## TODO\n\nAdd data streaming functions! ANYONE WANT TO HELP ADD THESE?\n\n## Overview of the lz4 algorithms\n\nLZ4 is lossless compression algorithm, providing compression speed at 400 MB/s\nper core (0.16 Bytes/cycle). It features an extremely fast decoder, with speed\nin multiple GB/s per core (0.71 Bytes/cycle).\n\n\n## References\n\nAt least two other R packages, the\nhttp://www.bioconductor.org/packages/release/bioc/html/gdsfmt.html package from\nthe Bioconductor, and https://github.com/fstPackage, use the lz4 library.\nHowever both packages are sufficiently specialized implementation that I\ndecided to write this much simpler, limited package with a focus only on\ncompression to promote software modularity.\n\nSee http://www.lz4.org for more on lz4.\n\n\n## Status\n\u003ca href=\"https://travis-ci.org/bwlewis/lz4\"\u003e\n\u003cimg src=\"https://travis-ci.org/bwlewis/lz4.svg?branch=master\" alt=\"Travis CI status\"\u003e\u003c/img\u003e\n\u003c/a\u003e\n\u003ca href=\"https://codecov.io/gh/bwlewis/lz4/branch/master\"\u003e\n\u003cimg src=\"https://codecov.io/gh/bwlewis/lz4/branch/master/graph/badge.svg\"/\u003e\n\u003c/a\u003e\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fbwlewis%2Flz4","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fbwlewis%2Flz4","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fbwlewis%2Flz4/lists"}
