There are in fact two completely separate notices.
The package sn will be deeply re-designed, both to incoroporate
new theoretical developments and to accomplish some standard features
of R packages. Therefore starting from the current release,
no major changes will be incorporated, before the new major version is ready.
Until then, only bugs will be fixed or changes required by the R Development
Team to accomplish some new features of R.
When the new version will be realised (identified by some 1.x-y version
number), its working and facilities will be somewhat different from the
current one. Therefore, it is not advisable that one develops a lot of
code under the assumption that certain functions will still be there.
The following are broad guidelines about the possible changes:
you can trust that functions Xsn, Xst, Xmsn, Xmst,
where X stands for any of d, p, q, r,
will still exist (only those combinations which do exist now, of course)
and work very much the same; the same is likely
to hold for T.Owen, zeta, sn.cumulants, st.cumulants;
be confident that the functions whose name include mle
or fitwill change or even disappear,
at least with that name;
the other functions have an intermediate (subjective) probability
I am aware that this can cause some inconvience, regrettably. This is
why this announcement is made well before the release of the new code.
Also, bear in mind that the current version numbering 0.x-y was chosen
exactly to signal that it is still experimental code, hence subject to
I do not know when version 1.x will appear. It is not only a matter of
writing code, but also of completing some supporting theoretical work.
It is even more difficult to state anything on the production of a
porting of version 1.x to Matlab. Volunteers to take on this
responsibility are welcome.
Versions prior to the current one, 0.4-2 (2006-10-26), contained
a bug in function rmst. If you have an older version,
please upgrade, and possibly re-run simulations if case of important
work using rmst. I apologize for this problem.
The function rst is not concerned with this issue.
