Hi R,
Again the problem in Bloomberg, I give the below code,
con =
blpConnect(show.days=trading,na.action=previous.days,periodicity=da
ily)# connecting Bloomberg
div - blpGetData(con,IBM US
Equity,EQY_DVD_HIST,start=as.chron(as.Date(01/01/2005,
%m/%d/%Y)),end=as.chron(Sys.Date()))
You need to print the result of an expression if used from source().
Autoprinting only occurs at the top level.
E.g.
% cat systest.R
print(system.time(for(i in 1:100) mad(runif(1000
source(systest.R)
user system elapsed
0.140.000.20

Dear All,
I tried to aggregate the rows according to some factors in a data frame.
I got the

I now rarely use Word; if the size of the wmf as fixed by the win.metafile
is smaller
than the size of the page within the margins you should have no problem.
So for letter size 8.5 x 11 inches with 1 inch margins and allowing 0.5 in
for a label
you coud have a landscape mode wmf size of height

The problem is that the phase data is reported as the residual

For instance if the phase is 10.359 rd then:
Hi,
I am a bit unclear if svyglm with family=gaussian is
actually a normal linear model including weighting.
The goal is to estimate a normal linear model using
sample inflation weights.
Can anybody illuminate me a bit on this?
Thanks a lot!

I understand that it is simple to create data with a specific

Thank you for the suggestions from Professor Ripley and Steve Elliot. I see now
why my data are unbalanced even though I don't have any missing data.
I think I should use other methods designed for unbalanced data, but does using
lme with plate as a random effect also help to fix this problem?
