prod(0, 1:1000) ; 0 * Inf etc
I think most of us would expect prod(0:1000) to return 0, and ...
... it does.
However, many of us also expect
prod(x1, x2) to be equivalent to
prod(c(x1,x2))
the same as we can expect that for min(), max(), sum() and such
members of the "Summary" group.
Consequently, prod(0, 1:1000) should also return 0,
but as you see, it gives NaN which may be a bit puzzling...

Have you ever experienced this problem with REAL in a C code
Dear all,
I'm currently experiencing big troubles with my C code called by .Call
in a R function.
I know this may not be the right place for such things but these errors
are driving me crazy. And I hope other people may have already
experienced these problems so that they could give me good suggestions.
Sorry if I'm completely out of topic.
Well let's go...

Suggestion for the optimization code
Dear list,
Here's a suggestion about the different optimization code. There are
several optimization procedures in the base package (optim, optimize,
nlm, nlminb, ..). However, the output of these functions are slightly
different. For instance,
1. optim returns a list with arguments par (the estimates), value the
minimum (maxima) of the objective function, convergence (optim

Problem in conditional looping
Respected All,
I am writing a program in R and facing some problem with applying "if statment".
Program first draw random numbers from bivariate normal distribution
then compute variable say Pi and Pij from that sample and
then further computation
.....
.....

In some samples Pij is appearing with negitive sign and ultimately
resulted in an negative variance estimator.

How to generate R objects in C?
I'm in the process of coding a parser (in C) to generate R entities
(vectors, lists, etc.) from a text description (different from R).
The basic parser works, and now I need to tell it how to create R
entities. I need to be able to create character vectors (for unicode
strings), integers, floats, unnamed lists, named lists, boolean
values, and NA. With the exception of the two types of lists

Strange behavior of C compiled program

legend() in a multiple figure environment
Dear all,
there seems to be a problem with displayed legends when a multiple
figure environment is used, see the following example:
par(mfrow=c(1,2))
curve(dnorm,col=4,from=-4,to=4);
legend(-4,0.3,legend="curve",lty=1,col=4)
legend(-4,0.2,legend="curve",lty=1,col=4)
On my machines the first time the command legend() is issued the
legend box stretches over the curve.

Hello there,
I got a small problem about logical calculation:
we can get a sequene from a+b as below:

but when the sequences are logical. (I want to get (True,False) && (True, True) ==> (True, False), but when I do as below.

Adding .PDF files to a package

new as I am to developing packages for R-Project, I apologize on

The way I understand the Rexts.pdf document, I should add my .PDF

uninitialised value in R (PR#13476)

Checking package on Windows (and seemingly irreproducible errors in CRAN checks)
Hello,
I submitted a small package, colbycol, to CRAN. I developed it on Linux
and tested it on my Linux box and another Windows machine. Besides,
other people kindly tested it in their systems.
The package seems to "compile" correctly in r-forge for Windows. In
fact, you can find the binary package at

R CMD check: Error in .C
Function/file names are hypothetical. Say I have written myfunction.R,
which calls myfunction.c via .C("myfunction", ...).
I've compiled successfully myfunction.c via R CMD SHLIB myfunction.c
in the terminal. Then, in the R console:
dyn.load("myfunction.so")
source("myfunction.R")
test <- myfunction() # works fine
So everything is in order, myfunction works

text works with the postscript device?
Dear R experts,
R (0.63) does not seem to write me any text in a PS file.
Trying
x11()
plot(12)
text(5,5, "Hello World")
works fine.
Now I would like to have the same as a PS file.
postscript("foobar.ps")
plot(12)
text(5,5,"Hello World")
dev.off()
Gives me a PS file with the plot -- but without the
"Hello World".
Why? I'm completely clueless.
Ciao
