Contributors on R-Forge
Hi,
I've recently taken over maintenance for the "xtable" package, and have
set it up on R-Forge. At the moment I'm pondering what the best way is
to handle submitted patches. Basically, is it better to:
1) Be non-restrictive regarding committer status, let individuals
change the code with minimal pre-commit review, and figure changes can
be reviewed before

Returning highs and lows in R
I'm having trouble returning a rolling n period highest value for a data
set. For each day I want to calculate the highest value over the last 3
days. I am using the following packages: zoo, xts, quantmod and TTR.
Thanks, Jason

Symbolic eigenvalues and eigenvectors
Let's say I had a matrix like this:
library(Ryacas)
x<-Sym("x")
m<-matrix(c(cos (x), sin(x), -sin(x), cos(x)), ncol=2)
How can I use R to obtain the eigenvalues and eigenvectors?
Thanks,
John

functions one called inside another.I know that how to use C code in R if it

history() does not work?
Hi,
> history()
gives Error in savehistory(file) : no history available to save
although I can scroll throu history with C^uparrow an C^downarrow.
How can I make history() work and/or show the current history in a file,
so that I can choose from previous commands?
The web did not throw up anything useful.
TIA --Christian

Parallel computing on Windows (foreach) (Sergey Goriatchev)
foreach (or virtually anything you might use for concurrent programming)
only really makes sense if the work the "clients" are doing is substantial
enough to overwhelm the communication overhead. And there are many ways to
accomplish the same task more or less efficiently (for example, doing blocks
of tasks in chunks rather than passing each one as an individual job).
But more to the

I have to get the value of say 90th percentile of precipitation time series.. The series is of daily precipitation value of 96 years, I have to to get 90the percentile value of daily precipitation each year. If you know the R code or command for this please let me know.
I would appreciate your early response.
Thanking you,

How to open .rda file in R
Hi,
I have a file containing gene expressions written using the tillingArray package. I used load() and attach() to get the data into R. Both of them works fine. Now I want to see the contents of the file. How can I see the contents of the file?
Thankyou for your time.

R
Hello, just a couple of short questions that would be much appreciated.
Is there a way of putting a vectors inputs in size order from low to high?
And if I had a random list or TRUE and FALSE, is there a way of finding the 100th TRUE?
Thank you very much,

Working with large matrix
Dear All,
I have large matrix (46000 x 11250). I would like to do the linear regression for each row. I wrote a simple function that has lm() and used apply(mat,1,func). The issue is that it takes ages to load the file and also to finish the lm. I am using LINUX 64 bit with 32G mem. Is there an elegant and fast way of completing this task?
Thanks in advance.
Kind regards,

Temperature Prediction Model
Greetings!
As part of my research project I am using R to study temperature data
collected by a network. Each node (observation point) records temperature of
its surroundings throughout the day and generates a dataset. Using the
recorded datasets for the past 7 days I need to build a prediction model for
each node that would enable it to check the observed data against the
predicted data. How can

Nominal variables in SVM?
Hi,
The answers to my previous question about nominal variables has lead me
to a more important question.
What is the "best practice" way to feed nominal variable to an SVM.
For example:
color = ("red, "blue", "green")
I could translate that into an index so I wind up with
color= (1,2,3)
But my concern is that the SVM will now think that the values are

install package from CRAN
Hi,
I have a very basic question about install packages from CRAN on unix. I
only installed on Windows before. Should I use the command install.package?
The error message I got is
syntax error near unexpected token `"mvtnorm"'
Is it because I didn't set the path? Which path should I specify?
Thanks,

Looking for a better way to document my packages
Hi all,
Trying to do what my subject says.
As I'm trying to be better about making packages out of my code, I'd
like the packages themselves to be better, which means *.Rd-
documenting my code. The thing is, from years of programming other
languages prior to landing in the R pond, I've grown accustomed to
documenting my functions inline. I'm not just used to it, but I like

Putting together a constantly evolving package
Hi all,
I'm putting together some common code + data into a custom package,
everything is working out fine, but the ``R CMD INSTALL MyPackage``
call seems to take a particularly long time in the "**data" step:
$ R CMD INSTALL MyPackage/
* installing to library ?/Library/Frameworks/R.framework/Resources/
library?
* installing *source* package ? MyPackage? ...

Parallel processing question ...
I am experimenting with parallel processing using foreach and seem to be
missing something fundamental. Cool stuff. I've gone through the list and
seen a couple of closely related issues, but nothing I've tried seems to
work.
I know that the results from foreach are combined, but what if there is more
than one variable within the loop? Below is a snippet (non-functioning) of
code that I

As a package author, is there a way to specify that your package is architecture (x86_64) specific?
Hi,
Essentially: subject line says it all.
I've created a package that wraps an external c++ library (which I
didn't write) that only successfully compiles on 64bit machines.
I'd like to make the package broadly available, but is there a way to
get it on CRAN if the 32-bit builds break by specifying its 64-bit
only somehow?
Luckily, I've ./configure'd my
