Hello,
I apologize if this is not the list for package announcements. Having
said that I've released a package called rprotos which implements a
simple
serialization using Googles protocol buffers[1].
The package also includes some miscellaneous functions for writing/
reading variable length encoded integers, and Base64 encoding/decoding
related functions.
The package can be downloaded from http://ml.stat.purdue.edu/rproto_1.0.tar.gz
it requires one to install libproto (Googles protobuffer library)
Brief Description:
The R objects that can be serialized are numerics, integers,strings,
logicals, raw,nulls and lists.
Attributes of the aforementioned are preserved. NA is also
preserved(for the above)
As such, the objects include factors and matrices.
The proto file can be found in the source.
Todo:
Very possible though needs some reading on my part: it is possible to
extend this to serialize functions, expressions, environments and
several other objects.
However that is some time in the future.
Regards
Saptarshi
