A new version of my DSE package for multi-variate time series analysis
now available at <www.bank-banque-canada.ca/pgilbert>. I am trying to
out some minor glitches with the new R 0.90 graphics before I submit it
to CRAN. Much of the underlying code has been re-worked and reorganized
new version. In particular, the use of model and data constructors has
more formalized and the internal structure of these objects, while still
documented, is considered "opaque."
I have separated out a "syskern" package which tries to provide a kernel
routines to isolate OS differences and a few Splus and R differences.
people, the most interesting part of this is probably the approach to
which provides a convenient way to generate the same random experiments
I have also separated out a "tframe" package which provides a kernel of
routines for programming time series methods. These allow a programmer
write most code in a way that is independent of the time representation
the class of the time series data). So, for example, the use of tsp() is
because it is specific to certain classes of time series.
The changes to the underlying structure necessitated a substantial
the user's guide, so I am taking the opportunity to bring the guide
with respect to R. A draft of the guide is available at the above web
postscript and pdf files. The first nine sections, which cover material
in the previous version of the guide, are now mostly complete and I hope
correct. I would certainly appreciate comments. Some later sections,
cover new material, are still missing or incomplete.
The help has largely been converted to integrate with R's help. I have
not yet worked through all the examples, many of which were written with
fictitious data in mind, so it will be some time before "R CMD check
dse" works, however, most of my tests work in both Linux and Solaris.
which cover a large part of the package. The comparison tolerances on
the tests had to be relaxed in order to pass with R on Linux and R and
in Solaris. I would appreciate feedback about how the tests work on
