That would certainly indicate a highly non-standard and potentially
dangerous configuration of the wuftpd that runs on ftp.ci.tuwien.ac.at

/etc/ftpaccess should contain a line like this

        upload home/ftp /incoming yes  root sysadmin 0664 

All version of wuftp that I came across would even set the permission
to 0664 by default, that is without the above explicit entry in
/etc/ftpaccess to a sane 0664. I recommend the ftpadmin look into this
matter and makes sure that things are fine ...

Brian, I don't think it is appropriate for you to criticize me for
letting people know that I have uploaded my port. Nowhere have I
hidden the fact that the package is a port of an S package and nowhere
have I removed Joseph's and Jane's authorship notices in the code or
documentation. In fact additionally, following R tradition, I have
clearly mentioned them as authors in the DESCRIPTION file.

Actually converting the Fortran code to double and making it compile
cleanly was more work ... The Rd files where generated from the
original tex document by means of a little perl script. This explains
also the poor quality of the Rd files: What's the best way of expressing
math such as $\sigma^2$ in Rd? Is there a way expressing this sort of 
math in Rd, that will preserve the tex expression for the latex docs
generated from Rd and at the same time translate into something legible in
the html docs?

Let me know which example and I will correct it.
