reading a ".mdf" file in R
Hi,
I have a very large ".mdf" database (36 GB) that I want to import to R.
I'm using a computer with 64 GB of RAM, running on windows server 2008 R2
with SQL.
Could anyone guide me through the process. I have absolutely no idea what to
do.
Thanks,

nomianl response model
Is there a way to estimate a nominal response model?
To be more specific let's say I want to calibrate:
\pi_{v}(\theta_j)=\frac{e^{\xi_{v}+\lambda_{v}\theta_j}}{\sum_{h=1}^m
e^{\xi_{h}+\lambda_{h}\theta_j}}
Where $\theta_j$ is a the dependent variable and I need to estimate
$\xi_{h}$ and $\lambda_{h}$ for $h \in {1...,m}$.
Thank you,
Mauricio Romero

Integrate a 1-variable function with 1 parameter (Jose L. Romero)
Hey fellas:
I would like to integrate the following function:
integrand <- function (x,t) {
exp(-2*t)*(2*t)^x/(10*factorial(x))
}
with respect to the t variable, from 0 to 10.
The variable x here works as a parameter: I would like to integrate the said function for each value of x in 0,1,..,44.
I have tried Vectorize to no avail.
Thanks in advance,

summary statistics for grouped data
Hello list:
Is there an easy way (preferably through one of the standard R packages) of obtaining summary statistics for grouped data? I could split the data into classes by hist, and then progressively calculate all the "columns" i need to obtain the mean and standard deviation, but i was looking for a single function that could do that with a data vector.
Thanks in advance,
jose

MS Exchange SMTP Login problem
Hello,
I'm using dovecot & postfix to bring smtp auth to our customers. Normal
mail clients have no problem at all and I'm so satisfied.
However, we're having problems with Microsoft Exchange server clients.
We're using our postfix-dovecot server as smarhost for several Exchange
Servers, and we wish to use TLS + basic authentication for these
outgoing mails.
But it seems that

He's asking about the -march option which should work either way.
Also, the driver-driver should be in the sources that they're using even still.

[LLVMdev] llvm-gcc and -march
Hi,
I apologize if I am not asking on the right mailing list.
I am using the llvm-gcc4.2 from MacPorts.
https://trac.macports.org/browser/trunk/dports/lang/llvm-gcc42/Portfile
llvm-gcc does not seem to accept the -march flag. This is the error,
I got:
cc1: error: unrecognized command line option "-march"
The port developer asked me to find out if this is a known issue.

Converting a S-plus file.
Hello all.
I've got a little file which is from S-Plus. The problem is I don't
own a copy of said program, and R won't read it.
I wonder if there's a caritative soul here who could export the file
to some other format (csv, or even excel!) and send it back to me.
Thanks in advance.

The -arch option is handled by Apple's "driver-driver", and the MacPorts build is probably not using that. See the driverdriver.c source file in llvm-gcc for details.

Full HTTPS support
Hi!
I've been giving support for streaming and streamcasting over HTTPS...
Everything started while giving streaming support to my website. When I
read a console error (or was it a warning?) on Chrome, when the browser
accessed to an http:// resource from an https:// domain.
Then I decided to fix it by the clean way.
I don't need official support yet... but if you don't mind to
