My first R-program
Sorry, I pasted the wrong file in earlier... this is the correct one:
pValCalculator(b, n=20, m=20)
{
ind <- 1:min(c(n,m))
prob <- (1-pnorm(b,sd=std*sqrt(ind)))
prob1 <- sum((n-ind+1)*(m-ind+1)*prob)
prob1
}
inputData <-
scan("/users/lvssso/projects/LAMA/output/pValLamaScore.tmp", list(block1
= "",block2 = "",width1 = 0,width2 = 0,alignment = 0,score

attach
Hi all,
I have a question regarding the memory usage for the attach function.
Say I have a data.frame inputdat that I create with read.csv.
I would like to know what happens on the memory side when I use
attach(inputdata)
Is there a second allocation of memory for inputdata?
Then I'm using eval on a expression which depends on the columns of
inputdata. Is it better not to use attach

DLL Memory Problem
Hello,
I have created a .dll file using G77 and MinGW on my PC (Windows
2000). After using dyn.load to bring it into R2.0.1, I then call the .dll
through the function ccprox shown below. It returns the correct
values. If I run it a second time though it returns different values, so
it seems something is being placed oddly in memory.
If I unload and reload the .dll it works again the first

Problem Writeing a pipe using R (stdin is consumed)
Hi everybody,
I a, trying to use R as a pipe like this:
cat inputData | R --silent RCommandFile >outputData
The RCommandFile would contain something like readLines(stdin()).
I have tryed various things and none did work cleanly.
One possible solution is to use the pipe() function inside R and to pass in the "cat inputData" however this is not very convenient
since I would like to

[LLVMdev] Alignment attribute of function arguments
Hello everyone,
Hopefully a simple question. How can I access function argument alignment
information? If my code has something like this:
void foo(short * __restrict __attribute__ ((aligned(8))) InputData){}
...as I deal with argument (InputData) can I get the alignment info set for
it?
Thanks!

Arrange elements on a matrix according to rowSums + short 'apply' Q
Greetings,
My goal is to create a Markov transition matrix (probability of moving from
one state to another) with the 'highest traffic' portion of the matrix
occupying the top-left section. Consider the following sample:
inputData <- c(
c(5, 3, 1, 6, 7),
c(9, 7, 3, 10, 11),
c(1, 2, 3, 4, 5),
c(2, 4, 6, 8, 10),
c(9, 5, 2, 1, 1)
)

problem post request with RCurl
Hi, I am trying to use a CGI service (Pubchem PUG) via RCurl and am
running into a problem where the data must be supplied via POST - but
I don't know the keyword for the argument.
The data to be sent is an XML fragment. I can do this via the command
line using curl: I save the XML string to a file called query.xml and
then do

please help on frag polynoms
hi there,
can anyone help me on the topic of frag polynoms?
i just heard of a friend of mine, that i could build in a functioon called
fragpoly (he was talking of such a function in the 'stata' language) in order
to improve my process of finding an optimal linear model.
instead of trying a vast amount of transformed inputdata to find the best
fit and then step backwards down to e.g.

fix sign of a coefficient in formula
Dear R users & experts,
I'd like to create a model using lm (or glm) under some constraints of
how coefficients for each component could look like (sort of a range of
coefficients that should be allowed).
So let's go for an example :
model=lm(age ~ eyecolor + height, data=inputdata)
So let's suppose that R pops out a model with positive estimates for the
coefficients eyecolor

NLS sensitivity to start= values or poles in data range
Greetings R-help! I'm fairly new to R and am trying to expand my knowledge beyond using R for simple summary statistics and basic tests. To that end I am attempting to write an interactive R-script that will perform a general rational function fit to a given dataset based on the example given at http://www.itl.nist.gov/div898/handbook/pmd/section6/pmd64.htm.

VQ generation utilities ready + usage instructions
The VQ codebook generation utilities are more or less ready to go. Minor
things are left to do, but those will have to be handled as I to them :-)
The next thing to do is complete the interface to get compression modes and
codebooks to the library for encoding (minor stuff), and then arrange how
exactly the MDCT residue is filtered through the codebooks.

Setup of discontinuous stream demux
I am putting together an ogg mux/demux application
which uses two logical streams. One is a vorbis stream,
the other is some application specific data.
This came together really quickly, following the ogg/vorbis
documentation it took only a few hours to get it up and running.
Just a small question...
My application stream is currently running as a continuous stream
but really I want it to be

Segmentation fault while using Mclust function of mclust library in R-2.0.1
Hi, all;
I got an unusual error while using mclust library 2.1-7 on R 2.0.1.
When I tried to run Mclust(rnorm(100)), I got segmentation fault error.
Does anyone know what causes this problem?
I came across the same problem even when I tried to run the example shown in
Mclust help using iris data.
Thanks in advance,
