Command completion of the R binary / Ubuntu
Dear Deepayan and dear list,
I notice a small inconsistency with the command completion of the R CMD
check. --no-latex is deprecated sincs R 2.12.0 and defunct since 2.13.0
but the command line completion still suggests it:
cb at cbdesktop:~/r-devel$ bin/R CMD check --no-<here I hit tab>
--no-clean --no-examples --no-latex --no-vignettes
--no-codoc --no-install

Needed: Beta Testers and Summer Camp Students
Greetings.
I'm teaching linear regression this semester and that means I write
more functions for my regression support package "rockchalk". I'm at
a point now were some fresh eyes would help, so if you are a student
in a course on regression, please consider looking over my package
overview document here:

Package snow: is there any way to check if a cluster is "acticve"
Is there a 'proper' way of checking if cluster is active. For example, I create a cluster called .PBcluster

set working directory to current source directory
Hi all,
Is there a way to get cran R to set the working directory to be wherever
the source file is? Each time I work on a project on different computers I
keep having to set the working directory which is getting quite annoying.
Thanks,

--as-cran / BuildVignettes: false
I have packages where I know CRAN and other test platforms do not have
all the resources to build the vignettes, for example, access to
databases. Previously I think putting
BuildVignettes: false
in the DESCRIPTION file resolved this, by preventing CRAN checks from
attempting to run the vignette code. (If it was not this, then there was
some other magic I don't understand.)

Help with 2-D plot of k-mean clustering analysis
Hi, all
I would like to use R to perform k-means clustering on my data which
included 33 samples measured with ~1000 variables. I have already used
kmeans package for this analysis, and showed that there are 4 clusters in my
data. However, it's really difficult to plot this cluster in 2-D format
since the "huge" number of variables. One possible way is to project the

OrgMassSpecR peak area issue
Hello!
I am having an issue with the OrgMassSpecR package. I run my HPLC using a
DAD detector. My raw data is exported form chemstation as a csv file. I
then upload the csv into Rstudio no problem. Using the DrawChromatogram
function, I get a nice chromatogram, and my retention time, peak area, and
apex intensity values are given as well.
The problem comes with the peak area value given. The

Outlier removal by Principal Component Analysis : error message

I am currently analysis Raman spectroscopic data with the hyperSpec package.

I am currently trying to remove outliers thanks to PCA just as they did in

R datasets ownership(copyright) and license
Dear R Developers,
Recently filed (and dismissed ;) ) law suit by Astrolabe against tz
database developers caused a lot of media-press and discussions and
created some kind of precedence in the USA [3]. But also it imho showed
that similar attacks might happen in the future, and possibly against
data sets which are not that obviously "factual" thus after all might
fall under copyright

predictive accuracy
I am trying to develop a prognostic model using logistic regression. I
built a full , approximate models with the use of penalization - design
package. Also, I tried Chi-square criteria, step-down techniques. Used
BS for model validation.
The main purpose is to develop a predictive model for future patient

CRAN policies
CRAN has for some time had a policies page at
http://cran.r-project.org/web/packages/policies.html
and we would like to draw this to the attention of package maintainers.
In particular, please
- always send a submission email to CRAN at r-project.org with the package
name and version on the subject line. Emails sent to individual members
of the team will result in delays at best.

SweaveInput + keep.source = TRUE trouble
Dear all,
I have trouble with R-beta sweaving files that include definitions with
\SweaveInput in combination with keep.source = TRUE
Symptom:
SInput is taken from too far down the input file (the shift is the number of
lines of the included file). Is that known? Searching didn't turn up anything,
yet I think there are more people than just me using keep.source.

force apply not to drop the dimensions of FUN results ?
Dear R users,
Here is my problem:
I have an array with at least four dimensions:

I'd like to apply a function to each occurrence of the matrix (3x6)
defined by the last two dimensions. This interpolation function always
return a matrix of the same dimensions as its argument:

R and Matlab
Dear Group,
I am looking for ways to use R and Matlab. Doing the data transformations in
R and using the data in Matlab to analyze with some pre-defined scripts.
Any good ways to transfer the data into matlab in its most recent version?
I tried using R.matlab but the writeMat output is not readable by Matlab.
I just need to output a data.frame and read it as is into matlab where I can
