Hi Dirk!


FYI we made two announcements on the mailing-list describing the changes
in the packages.

not smooth? To recall, we made important changes in the S4 objects.
So, we decided to rename the packages to avoid backward compatibilities.

As you might have noticed, the old packages are still available on CRAN.

And when one loads the old packages, one gets a banner
encouraging to switch to the new version.

The ChangeLog is a good point. I have started to add a ChangeLog in the
packages.

You can get the list of all Rmetrics packages from our website with

source("http://www.rmetrics.org/Rmetrics.R")
pkgsRmetrics() # will give you the list of the packages and 
install.Rmetrics() # should install all packages.

or search all Rmetrics help pages at http://help.rmetrics.org

These are new tools and we will announce them on the mailing-list as
soon as we have finished our ebook on portfolio optimization
with Rmetrics.

Best regards,
Yohan
