summing and combining rows
Hello,
I have a data set that needs to be combined so that rows are summed by a
group based on a certain variable. I'm pretty sure rowsum() or rowsums()
can do this but it's difficult for me to figure out how it will work for
my data based on the examples I've read.
My data are structured like this:
Plot SizeClass Stems
12 Class3 1
12 Class4

What exactly is strange, apart from posting a question as a bug report?
Please do read the R FAQ and don't misuse R-bugs to ask questions.
Hint: you most likely specified a non-existent time. When did your locale
switch to DST in 1993? I don't know, of course (you haven't told us your
locale) but I bet it was that day. That means the time you specified does
not exist if your locale

Design flaw with Fixtures?
I''ve been trying to add unit testing for collection of models with
complex relationships -- and failing miserably.
Because of the complexity of the relationships, I''m using a database

of each other. The basic problem is the DELETE then

Again: Occasional problem with POP3-Download
Hello everyone,
in february I posted the mail below[1].
I can now reproduce the problem. When filling up a mailbox with postfix'
smtp-source with dozens of identical mails, then it is never possible

Occasional problem with POP3-Download
Hello everyone,
I have two mailservers [1] running dovecot. Mail store format is
maildir. Every once in a while I have the following problem: When a User
downloads his mail via POP3, the client says something like "the server
has closed the connection unexpectedly, and gives this reason:
[...blahblah...]".
One can now cancel the download, and restart it, and the problem shows
up again
