I wonder if anyone has written some additional R code to perform
weighted logistic regression in the way of SAS PROC LGOISTIC WEIGHT
statement. I want to weight the sample using a vector of probabilities
generated from Dirichlet distribution.
It is known that the R function glm has a WEIGHT

You could write code automate this, but it's easy enough to look at

I am afraid that R cannot provide the function we want. But I can use R to
write a function to do the specific factor analysis. Because the functions

I do not know whether R can do that. However, you can accomplish that
easily with
If this is about more than a handful files, then it is really painful
to do it with OpenOffice.org or LyX, I guess.
You can use imagemagick, this is fairly standard on Linux. Then it is
something like this, assuming you have bash:
for f in *.png; do convert $f ${f%png}pdf; done

Hi Daren,
Can R (out)do Emacs? I think you just need to ?Sweave a little.

Dear readers,
S-Plus have a rts function (Regular Time Series), which is used like so:
fveks-read.csv('http://louise.hoffman.googlepages.com/veks.csv',header=TRUE,sep=',')
attach(fveks)
acf(ts.intersect(rts(HC.f),rts(Ta.f),rts(GR.f),rts(W.f)))
Warning the csv file is 750kB.

Use ts() in R. See e.g. the chapter on times series in MASS4.
Just replacing rts() by ts() in your example gives what I guess you were
expecting in S-PLUS.
