OT: DOE - experiments for teaching
Hi,
I'm sorry for this not being related to R but I think this is a good
place to ask. I'm looking for DOE examples(experiments) that can be done
at home or in class, such as Paper Helicopter, Paper Towel etc.. I'm
thankful for any comment.

Using R to process spectroscopic data
Dear R-users,
I would like to process some spectroscopic data with R, and I was hoping
some people might have some example code on how to do this.
I would like to be able to do the following things:
* Detect outlier-spectra -> This can be done by using scoreplot from the
pls package
* Determine the range of the spectrum to be used -> For this, I should
be able to calculate the regression

efficiency in merging two data frames
I have two data sets about lots of companies' stock
and fiscal data. One is monthly data with about
144,000 lines, and the other is quaterly with about
56,000. Each data set takes different company code.
I need to merge these two together. I read both ask
cvs. And the other file with corresponding firm code.
Now I have three data sets. return$PERMNO,
account$GVKEY. id is the data frames

How to strip one term from a data.frame? + How to write long line in script?
I need to run a regression with 14 normal variables
and 20 dummy variables. All the data is in a huge
data.frame df. But there is some extra intermediate
item in the same data.frame too. It will be nice I
can strip off those terms and run lm(). Also, is
there a simple way to write the formula, for example,
just specify the y term, all other term in data.frame
should be x_i. Or is there some

general help on R and factor in R and a few simple comment from a newbie
Hi. I am starting to learn R for a course project. I
am relative OK c++ programer. I found the R is very
different. I have read the "an introduction to R". I
have to say it is not very newbie friendly. It does
not explain many things clearly. And unfortunately,
there is not too much introductory materials available
on-line. I do not want to buy a book.
For example, I found

devide data into decile
I guess this is really basic. But I do not find an
answer yet. I have a big data.frame. I would like to
divede them into 10 deciles accounding to one of its
member. Then I need a number for each decile with
some computaion within each group. How to devide it?

Effect display of proportional odds model
Dear useRs,
I very much like the effect display of the proportional odds model on
page 29 (Figure 8) of the following paper by John Fox:
http://socserv.mcmaster.ca/jfox/Papers/logit-effect-displays.pdf
It really gives a very concise overview of the model. I would like to
use it to illustrate the proportional odds mixed models we fit here for
a project on Diabetes but I can't seem to reproduce

plot filled.contour over continent map
Dear all,
As a newbie in R I would like to do the following (simple?) thing:
to plot a filled.contour plot over a map showing country boundaries (e.g. for Europe)
What i do is:
map('worldHires',xlim=c(-10,40),ylim=c(35,70),boundary = TRUE,border=0.1)
map.axes()

Patch for 'packet.c' in openssh-3.6.1p1
Hello,
I just managed to compile openssh-3.6.1p1 on Ultrix/MIPS. One of the fixes
needed for this is the following. It's because of:

poisson mean hypothesis
Dear R-users,
Is there a way to get p-values for a one-sided hypothesis test about a

The current solution is 8 years old and is reaching its end of life.
The reason we are also looking into gluster is that we like that it uses
standard components

weird question about lm() and data.frame
I am still battling with my project :(
I have a line like this
lm(month.model$next.ret~.,month.model,na.action=na.omit)
month.model is a data frame with lots of columns. One
of them is "Oth", a dummy variable. I checked
month.model, there are two rows with number 1 and
others are either 0 or NA. the two rows with Oth==1
have no NA. I have totally about 900 rows. But after

gluster for home directories?
Hi,
Why do you need to replace your existing solution?
If you don't need to scale out due to the capacity reasons, the async NFS server will always outperform GlusterFS

Gluster very poor performance when copying small files (1x (2+1) = 3, SSD)
Hi,
As I posted in my previous emails - glusterfs can never match NFS (especially async one) performance of small files/latency. That's given by the design.
Nothing you can do about it.

gluster for home directories?
Hi,
We are looking into replacing our current storage solution and are
evaluating gluster for this purpose. Our current solution uses a SAN
with two servers attached that serve samba and NFS 4. Clients connect to
those servers using NFS or SMB. All users' home directories live on this
server.
I would like to have some insight in who else is using gluster for home
directories for about 500

Gluster very poor performance when copying small files (1x (2+1) = 3, SSD)
Hi,
I've done some similar tests and experience similar performance issues
(see my 'gluster for home directories?' thread on the list).
If I read your mail correctly, you are comparing an NFS mount of the
brick disk against a gluster mount (using the fuse client)?
Which options do you have set on the NFS export (sync or async)?
