I am developing an R package that can make (optional, but strongly
recommended) use of a number of external compression algorithms. What is
the best strategy if I want to distribute this as an R package? Because
the package is for reading large external data sets, the package will
probably not be very useful without compression.
- Make a hard dependency on all external libraries and make user
manually disable it if they cannot install a library for some reason?
- Make no dependency on external libraries and have the user compile it
manually if they want compression?
- Look for installed libraries and use only these? (If so: How would I
do this during the installation of an R package?)
- How does this work on Windows?
The possible compressions are: blosc, zlib, bzip2, lz4, xz
Cheers,
Guido
