[R] New RH7.2 rpms for R-hdf5 support available

HDF5 is a high quality data storage format from NCSA
(http://hdf.ncsa.uiuc.edu/index.html) Marcus Daniels of the Swarm
Development Group has made available an R library called hdf5 which
allows loading and saving of data in hdf5 format. The source for his
library is here:

ftp://ftp.swarm.org/pub/swarm/src/testing/hdf5_1.4.7.tar.gz

I prefer to use RPMs to maintain software across many linux systems, so
I  have the RPM for this R library here:

http://lark.cc.ukans.edu/~pauljohn/software/R-hdf5-1.4.7.R1.4.0-1.i386.rpm

The SRPM is in the same directory.

Please note in order to use this you have to have hdf5 (duh!) and I have
the rpm for the required version 1.4.2 in that same software directory.
   Because of slight changes in RH7.2 in the ssl libraries, it is
necessary to use the RPM I built explicitly for RH7.2:

http://lark.cc.ukans.edu/~pauljohn/software/hdf5-1.4.2-1RH72.i386.rpm

I've been providing these RPMS for more than..., well, for a long time,
and I expect to continue, so you have no need to fear  you are adopting
a format that won't be supported for long.  And, even if I quit, the
NCSA folk have bent over forwards and backwards to make the hdf5
libraries build on many many platforms.

This data storage format has many things to recommend it, none of which
I am technically qualified to explain to you :)  But, in R you can make
use of hdf5save to store the data in a format that might be communicated
to another platform without corruption. If you have a newish copy of
Swarm on your system, then you can make hdf5 datasets that have vector,
or "time series" sorts of data in them.  High precision storage of
floating point numbers, etc.
