Dear R-user group

I am currently running R-0.90.1-1 for LinuxPPC on my PowerBook. Few days
ago
I have seen at CRAN that a new R-package exists, namely
R-base-with-hdf5-0.90.1-2.
Sorrowly, I could not find any explanation, what the difference to the
other package is.

I have downloaded the "Introduction to HDF5 Release 1.2" from
hdf.ncsa.uiuc.edu/HDF5.
It seems that HDF5 is a data format, wich overcomes some file size and
storage problems.

However, what is the advantage with respect to R?
Does this result in an improved memory model for R (or do I get
something wrong)?
Is it worth using this new version?

I have to work with very large tables (about 300,000 rows) so any
improvement in the
memory model of R would probably be an advantage.

Thank you in advance for your help.
