Calculating AIC for the whole model in VAR
Hello!
I am using package "VAR".
I've fitted my model:
mymodel<-VAR(mydata,myp,type="const")
I can extract the Log Liklihood for THE WHOLE MODEL:
logLik(mymodel)
How could I calculate (other than manually) the corresponding Akaike
Information Criterion (AIC)?
I tried AIC - but it does not take mymodel:
AIC(mymodel)
# numeric(0)
Thank you!

Reading SPSS .por files
Does anyone know how to read SPSS .por (ie Portable) files? The foreign package only deals with SPSS .sav files and not with those with a "por" extension.

contextstack overflow
Hi all,
I´m an absolute beginner in R programming…I have a really long R-code with
many variables. When I run the program I always get an error at the same
place called “contextstack overflow”. Does anybody know what to do in this
case? Are there so strict limitations in R? If yes, is it possible to handle
it? How?
Thank you for any help!

Hi,
1. How do I construct 95% prediction interval for new x values, for example - x = 30000?
2. How do I construct 95% confidence interval?

edit.data.frame
Dear list,
Sometimes I have huge data.frames and the small spreadsheetlike
edit.data.frame is quite handy to get an overview of the data. However,
when I close the editor all data are rolled over the console window,
which takes time and clutters the window. Is there a way to avoid this?

How to get multiple Correlation Coefficients
Hi
I have used a polycor package for categorical correlation coefficients.
I run the following script. But there were no results.
Could you tell me how to correct the script?
Thanks in advance,
vars <- names(sdi)
for (i in 1:length(vars)) {
for (j in 1:length(vars)) {
paste(vars[i]," and ", vars[j])
polychor(vars[i], vars[j])
# corr
}
}

link my own C library using Rcmd SHLIB
Hi All,
I have already used gcc to creat a library, for example, it is called
"test.a", which includes many
c objects.
How to link my main "a.c" function to this library when I used Rcmd SHLIB
to complier my main c program?
I tried "Rcmd SHLIB a.c test.a". It does not work this way. Does anyone
have idea about this?
Thanks,

R on Windows XP x64
Hi,
I am running R 2.2.0 on the Windows XP x64. The mechanism of error hanlder
seems different. It will take a very long time to pop up a error message
diaglog box, even when some simple errors happen such as "Syntax error" or
"object xxxx not found". Does anybody have the similar experience? Thanks
a lot.
BTW: everything works fine under 32-bit Windows XP, error messages
