Testing Specific Hypothesis
Hi All!
I am interested in testing whether the means for the data I am investigating
are equal to a specific value - let's say 0.01. I have already run a
one-way ANOVA and know that the differences in the means are not
significant, so now I want to know what values the means take on. "otestme"
is the data I am working with (it would be hard for me to get into a form

Looping Through QuantMod Objects
Dear R Helpers,
I have run into a problem trying to perform a number of actions on a set
of quantmod data objects through a loop and I am hoping that this is an
easy problem for someone else as opposed to very difficult for me.
The example task is to get the first three objects of the quarterly
balance sheet for a number of companies from the getFinancials object and
put them together into a

lme fitted correlation of random effects: where is it?
The print method for lme *prints out* the fitted correlation matrix for
the random effects. Is there any way to get these values as an object in
R? I have examined the components of the lme object (called "junk" in the
example below) and the components of summary(junk) without finding these
numbers.
(How I did this: I dumped the entire lme object to a text file and then
used egrep to

testing diff for slopes and intercepts
I fit the model
fit<-lm(thresh~cond*Ne)
where
thresh is the reponse
cond is a factor with levels a, b, and c
Ne is a continuous indep var
I think of this full model as having three lines: thresh as a function of
Ne for each condition. Thus we have slopea, slopeb, slopec, inta, intb,
intc.

Using rsync for buidling Oracle standbys.
Hi,
We currently use rsync to create an Oracle standby on a target box from an existing standby by copying all the datafiles while the source standby is in recovery status. We are occasionally running into datafile corruptions being reported by oracle when it is recovering the new standby. Oracle support says they don't recommend copying files while the changes being applied to them unless

WAS: Call pickup (*8) on SIP devices. Bug #116
I've attached two SIP debugs in reference to bug #116. They are from
today's CVS build.
1. pickup.txt is a call from SIP(1) to SIP(2) with SIP(3) picking up the
call. After which, SIP(2) rings for about 30 seconds then stops.
2. hangup.txt is a call from SIP(1) to SIP(2) with SIP(1) hanging up before
the call is answered.
SIP(1&3) are Cisco 7960's and SIP(2) is a Polycom
