...about this? Also, I tried installing the downloaded source with >R CMD INSTALL hdf5_1.6.0.tar.gz and it failed because the 'configure' script of the package failed. Anybody had experience with this? If I can install with 'R CMD INSTALL', that's also good enough. Thanks. Zepu

...difficult to move them around. The spin-off package may be always automatically loaded as a basic one, but as discussed above, a cleaning grouping greatly helps learning and finding things. b) To R users The system (both the core and the specialized package) will be easier to learn and use. -- Zepu Zhang, zpzhang at uchicago.edu
