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
}

generic methods - in particular the summary function
Hi all,
I'm currently working on the fitdistrplus package (that basically fit
distributions). There is something I do not understand about the
generic function summary.
In the current version on CRAN, there is no NAMESPACE saying
S3method(summary, fitdist)
.
However if we use summary on an object send by fitdist function it
works fine...
According to R-lang, we have

legend with small colored boxes
Hi all,
I tried to a nice legend with small boxes filled with the colors used
for the plots. But it does nor work, boxes are always filled with black.
An example is here
plot(1:4,1:4)
lines(1:4,4:1, col="blue")
legend("top",leg=c("a","b"),col=c("black","blue"), fill=TRUE)
How could I specify the colors? the argument col.box is the

Question about plotting discontinuous data
Hi, I have a simple question that I just cannot figure out. I
have 2 corresponding columns of data, one column (X-axis) for
time (formatted thus: 8:30:01am = 830.1, 12:30:05pm = 1230.5,
and one column (Y-axis) for values.
When I attempt to plot the data using something like
plot(inputdata[,1],inputdata[,2],type="l");
I get breaks in the plot (since the time essentially jumps

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

rowSums, rowMean and rowCumSums?
Dear list,
Don't you think it could be useful to have in R base a function
rowCumSums, that compute cumulative sums for each row of a matrix?
My implementation of rowCumSums is
rowCumSums <- function(x) t(mapply(function(row)cumsum(x[row,]),
1:NROW(x)))
I'm sure it can be improved to have other arguments like na.rm or dims.
Is there any hope to have this function in R?

problem with symbol function
Hi all,
I use the symbol functions to draw circles. But the argument lty does
not work on windows but works correctly on my macbook:
x <- -4:4
y <- -4:4
plot(x,y,type="n")
symbols(0, 0, add = TRUE, circles = 1, inches = 1, fg="black",
lty="solid")
symbols(0, 0, add = TRUE, circles = 1, inches = 2, fg="black",
lty="dashed")

on the optim function
Dear useRs,
I have just discovered that the R optim function does not return the number of iterations.
I still wonder why line 632-634 of optim C, the iter variable is not returned (for the BFGS method for example) ?
Is there any trick to compute the iteration number with function call number?
Kind regards

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

R tutorial
Dear all,
I have just found a 'good' tutorial R for datamining. I think it
should be on the contributed docs.

Here is the link

What do you think?

AR(2) modelling
Hi useRs,
I'm trying to fit a basic AR(2) model with the 'ar' function. And when
I try to check the value of the coefficients, I could not find the
same value as the 'ar' function.
Here is my example:
myserie <- c(212, 205, 210, 213, 217, 222, 216, 218, 220, 212, 215, 236)

[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)
)

extended Kalman filter for survival data
If you mean this paper by Fahrmeir: http://biomet.oxfordjournals.org/cgi/content/abstract/81/2/317 I would recommend BayesX: http://www.stat.uni-muenchen.de/~bayesx/.
BayesX interfaces with R and estimates discrete (and continuous) time survival data with penalized regression methods.
If you are looking for a bona fide Bayesian survival analysis method and do not wish to spend a lot of time
