Hi Dave,
I run into this problem with windows 7 and 8. I used the latest
versions of r and ncdf as taken from icran.
I found my way around this problem breaking the files but it is a
petty that ncdf has this bug as it is a quite useful package.
Thanks,
Camilo

Dear R users,
I have written a couple of R functions, some are through the help of the
R group members. However, running them takes days instead of minutes or
a few hours. I am wondering whether there is a quick way of doing that.
Here are all my R functions. The last one calls almost all of
That worked great!
Best regards,
Chris

Yes Bert, I am a beginner in writing R functions. I just don't know what
to avoid or what to use in order to make the R functions faster.
When I run the individual functions, they run quite well.
However, calling all of them using the final function it becomes too slow.
So I don't know how to m

Have used the suggested solution (the second method, as it seems a bit
leaner) on my real data, and it works perfectly. Thanks.

Dear all,
I am using cv.glmnet in r and I have the following question: The default is
10-fold cross-validation, but it is not clear to me how many times are
repeated? Is it 50 repeats?
I am sore if me question will be very easy for some people!

I may not get your question, but you seem to be confusing the name of
an object, which is essentially a pointer into memory and a language
construct -- (correction requested if I have misstated! -- and the
"names" attribute of (some) objects. You can, of course, attach a
"lab" or (whatever)

Hello all,
We would like to use R to run Bekk-Garch with 2-group to 4-group financial

not BEKK-GARCH. Any suggestions on using R to do BEKK-GARCH test?

the density plot will give density for negative part also. of course I can

I wonder if there is a program to compute density for a user-specified

So this is an alternative method. The package can be installed from
source() rather than rebuilt. Although the warnings exist, the package
itself may still be useful. Can you let me know how to installed from
