Facter and arrays
Hi,
Is it possible to have an array as the output of a custom fact? And
then to pass it into a template in Puppet?
I currently have a fact that looks like this:
Facter.add("exports") do
setcode do
case Facter.hostname
when (/thishost/i):
[ "/local", "/local2" ]
end
end
end
& a template like this:

Failure to find definition
Hi,
I''m trying to set up apache2 under puppet, as in this recipe:

I have a file "apache2.pp" as shown there, and then a webserver.pp file
(see below).
On running puppetd on the client, I get this message:

sampling random groups with all observations in the group
Hi
I have a panel dataset with large number of groups and differing number
of observations for each group. I want to randomly select say, 20% of
the groups or 200 groups, but along with all observations from the
selcted groups (with the corresponding data).
I guess it is possible to generate a random sample from the groups ids
and then match that with the entire dataset to have the intended

package mgcv, command gamm
Hi
I am an engineer and am running the package mgcv and specifically the
command gamm (generalized additive mixed modelling), with random
effects. i have a few queries:

However, I would like to see the results as in vis.gam command in the
same package, with the 3-d visuals. It appears no such option is

Minimal build of R ...
Hi,
I'm trying to cross-compile R to javascript so that it can run in a web-browser. Take as long as you need to stop laughing. So, as I was saying - I want to try and get a build of R running in the browser. [If you're not familiar with it already, you might enjoy looking at emscripten.org. It's a remarkably capable tool for translating LLVM bitcode to javascript. Check out some of

confidence intervals for Harrell's c-index in survival setting
Dear All,
Is it possible to get confidence intervals for Harrell's concordance index or, equivalently, Somer's D using the rms package or in some other way ?
I have survival data it would be the c-index in the Cox model setting
Many thanks

negative Somers D from Design package
Dear R help
My problem is very similar to the analysis detailed here.
If we use the mayo dataset provided with the survivalROC package the estimate for Somer's Dxy is very negative -0.56.
The Nagelkerke R2 is positive though 0.32.
I know there is a difference between explained variation and predictive ability but I am surprised there is usch a difference given that even a non predictive model

A GLM for a parameter of the error distribution.
Dear Sir/Madam,
I am an experienced programmer that has had little exposure to R so
please forgive me if I am inaccurate in places. I have an objective with
which I can not find a solution. I would like to fit a GLM to binomial
data that includes r number of success from n trials. The GLM that I am
proposing describes P, the binomial probability of success. The link

Feature Request - Load Throttling
If you aleady are doing this - then thanks. But here's a feature I'd
like to see.
Rsync often puts a lot of load on the system because of high disk
access. I'd like to see rsync become "load aware" and to slow itself
down under high load levels. Seems to me that it could be something
fairly easy to add to have it check the load levels and back down so as
not to slow

graphs for pretest data
Is there an easy way to make graphs for the following data. I have
pretest and posttest scores for men and
women. I would like to form a 'titlted segment' plot for the data.
That is, make segments joining the scores,
with different types of segments for men and women.
Example data:
menpre <- c(43,42,26,39,60,60,46)
menpost <- c(40,41,36,42,54,58,43)

replace negative numbers by smallest positive value in matrix
Hi Group,
I have a matrix, and I would like to replace numbers less than 0 by
the smallest minimum number. Below is an
small matrix, and the loop I used. I would like to get suggestions on
the "R way" to do this.
Thanks,

they were half the speed comast was/is. I''ve looked into Speakeasy, since
I heard a few of ya talking about them. Since I had TDS, that kinda tells

how to prevent duplications of data within a loop
Hi All,
I had posted a question on a similar topic, but I think it was not
focused. I am posting a modification that I think better accomplishes
this.
I hope this is ok, and I apologize if it is not. :)
I am looping through variables and running several regressions. I have
reason to believe that the data is being duplicated because I have
been
monitoring the memory use on unix.
How can I avoid
