This package will not be maintained. Instead, use the better 'fst' package, see
http://www.fstpackage.org/, which now includes faster and better in-memory
fst::decompress_fst covered here,
as well as several file-based compression options.
Note that neither this package nor the fst package include proper streaming options to arbitrary connections...something someone should add to fst!
lz4 Data Compression/Decompression Functions
Easiest to install with the
devtools::install_github("bwlewis/lz4") library(lz4) ?lzCompress
Add data streaming functions! ANYONE WANT TO HELP ADD THESE?
Overview of the lz4 algorithms
LZ4 is lossless compression algorithm, providing compression speed at 400 MB/s per core (0.16 Bytes/cycle). It features an extremely fast decoder, with speed in multiple GB/s per core (0.71 Bytes/cycle).
At least two other R packages, the http://www.bioconductor.org/packages/release/bioc/html/gdsfmt.html package from the Bioconductor, and https://github.com/fstPackage, use the lz4 library. However both packages are sufficiently specialized implementation that I decided to write this much simpler, limited package with a focus only on compression to promote software modularity.
See http://www.lz4.org for more on lz4.
The code coverage is too damn low!
Because we're using a tiny fraction of the lz4 library capabilities, but checking all library lines of code. This is just an incentive to implement more of the lz4 functionality at the R level!
