Netbios over VPN
I am attempting to utilize BackupPC on a Fedora 14 server to backup a remote client.
As I understand, it's primary mechanism for finding clients is performing a nmblookup <clientname>
This works fine for computers connected to the local network.
My issue is extending ?Samba's? search to encompass our other network - the point-to-point VPNs
Using OpenVPN, we have a number of road

Formatting significant digits with trailing zeros
I need a function like signif(), but returns the rounded values as
character strings, formatted with trailing zeros where appropriate.
If anyone has one, I would sure appreciate a copy.
Thanks
-Don
Details:
signif() rounds a number to a specified number of significant digits,
for example:
> x <- c(2.503,2.477,0.1204)
> signif(x[1],3)
[1] 2.5
> signif(x[2],3)
[1] 2.48

RPM file download
I see a package "x246-0.120-5.20120303.el6 (i686)" available in my
Add/Remove Software tool. I can't find said package in any of the repos
I've searched through.
Can anyone point me to a link where I can download that package to my
local repo?

writing lm summary to file?
Hi,
I want to write the summary from a regression. I am doing this because I do not see a way of get the std error, tvalues from the coefficients diagnostic. n$coef does not give this only get the intercept and slope. I tried to use write and write.table and got error in both cases. I jumped thru the hoops below to no avail. Also note, this is in windows. I used to use unix, and do not

Creating the mean using algebra matrix

I wanted to create the mean using a algebra matrix.
so I tried this one:

(Calculates the matrix multiplication of the new3 * factorial).
But I get the following error message:

Pairwise n for large correlation tables?
Hello,
I'm using a very large data set (n > 100,000 for 7 columns), for which I'm
pretty happy dealing with pairwise-deleted correlations to populate my
correlation table. E.g.,
a <- cor(cbind(col1, col2, col3),use="pairwise.complete.obs")
...however, I am interested in the number of cases used to compute each
cell of the correlation table. I am unable to find such a

mixed-effects model using lmer
Hello R-users,
I have been trying to fit what I think is a simple mixed-effects model using lmer (from lme4), but I've run into some difficulty that I have not been able to resolve using the existing archives or Pinheiro and Bates (2000).
I am measuring populations (of birds) which change with time at a number of different sites. These sites are grouped into regions. Sites are not measured

Adam,
It seems that your attachment didn't make it through.
That aside, my experience with strange errors like those (random type
not implemented ones) has been that you may be looking at a memory
problem on you machine. Given that you can't replicate on another
platform (and the .csv file didn't come through), I would think it
wise to start there.
My 2c. And I love bacon too :)

finding a faster way to run lm on rows of predictor matrix
Hi, everyone.
I need to run lm with the same response vector but with varying predictor vectors. (i.e. 1 response vector on each individual 6,000 predictor vectors)
After looking through the R archive, I found roughly 3 methods that has been suggested.
Unfortunately, I need to run this task multiple times(~ 5,000 times) and would like to find a faster way than the existing methods.
