Frank,
Thanks for the reply so what I did in the interim was unistalled Hmisc
and chron and used version 3.0-2 of Hmisc which doesn't have the
dependency on chron, and reinstalled its version 1.1.4
However I still heave the issue, when I try to run the quantile command
on the given dataset.
Thanks,
~Lloyd

Lloyd - Charles Thomas Dupont will respond with the definitive
information on this but I think that the later Hmisc required chron and
it should not have. Thomas will fix that.
