Building packages in R - 'private' functions
Hello.
I am creating an R package that I'd like to submit to CRAN (OS Windows
XP). How do I distinguish among 'public' functions, e.g., those that are
intended to be called by users of the package and for which I am providing
documentation & examples, and 'private' functions, which are used
internally by the 'public' functions, but for which I do not wish to

Building R package: make pdf & _masked_by_GlobalEnv
Hi....
I am assembling an R package (under Windows XP, R v.2.3) and have a very
basic question. Running R CMD build does not generate a pdf. R CMD check
generates a .dvi, but I cannot figure out how to automatically create the
pdf. I thought from reading the "writing r extensions' manual that R CMD
build was supposed to generate the pdf. I am having no success using

using kernel density estimates to infer mode of distribution
Hello...
Is it possible to use "density" or another kernel density estimator to
identify the mode of a distribution? When I use 'density', the resulting
density plot of my data is much cleaner than the original noisy histogram,
and I can clearly see the signal that I am interested in. E.g., suppose my
data is actually drawn from two or more normal (or other)

using kernel density estimates to infer mode of distribut ion
This might be of interest:

(I was not able to get to the link, but google has a cached version.)
Prof. Marron's SiZer maps may also be of interest, but AFAIK the code is in
Matlab only.

dynamic variable creation in lists and data frames
Hi
I have a question about the creation of variables within lists in R. I am
running simulations and am interested in two parameters, ESM and ESMM (the
similarity of these names is important for my question). I do simulations
to generate ESMM, then plug these values into a second simulation function
to get ESM:
x <- list()
for (i in 1:nsimulations)
{
x$ESMM[i] <- do_simulation1()

problem with 'integrate'
Hello -
I am having a problem with the function 'integrate'. I am running R
on OSX (R 2.5.1).
I am trying to suppress the error message when 'integrate' attempts
to integrate across a parameter set giving a non-finite function
value. I'm using it in a MCMC / simulated annealing algorithm, and
it is entirely possible that some parameter sets will give non-

How allocate STRSXP outside of gc
Hi,
I am trying to figure a way to allocate a string SEXP so that gc() won't
ever collect it.
Here is a little bit of a background. Suppose I want to write a
.Call-callable function that upon each call returns the same value, say
mkChar("foo"):
SEXP getFoo() {
return mkChar("foo");
}
The above implementation doesn't take advantage of the fact that

R 2.1.0 scheduled for April 18
The release schedule has now been set with a release date on April 18.
The detailed procedure can be found at http://developer.r-project.org/
(it is not quite there yet, but will appear after a short propagation
delay.)
The main point for non-developers is that we start making alpha
tarballs on March 21 and beta tarballs on April 4. Only very simple
and/or critical bugs are fixed in the last

VERY TINY question: missing function to clear the console?
Hi,
for presentation purposes I would like to clear to whole console
window (like in a UNIX terminal: 'clear').
Is there such a function?
If not, I could image that is not too hard to write such a function.
Cheers,

Plot timer in a for loop
Hello,
This code works fine but is so fast I can't see anything but the last plot.
for (i in nrow(X)){
plot(as.numeric(d[i,])) }
I'd like to view a plot every 500 milliseconds, nrow(X) = 400. How?
Thanks

Process to both write to and read from (pipe/fork)?
Dear all,
I would like to start a process from an R program in such a way that
I can both feed input into the process and read the process's output.
It seems that in R, I can have a pipe for writing into another process's
input or a pipe for reading from another process's output, but not both.
Doing both necessitates forking, such that the child can start the
external process and

Precision
How precise is R numerically? For example I
wrote the following function for calculating
the volume of the ball inscribed in the
unit cube in m dimensions. In order to see what
happens in 40 dimensions, I created an output
of 24 digits. But how many are precise?
Thanks

fork package problem
I have been using the fork package on a cluster to spawn jobs. I have
noticed that I end up with many "R defunct" (zombie) processes following
the use of fork that do not die completely until I close down R.
Initially, I thought it may be my code but I ran the example from the
latest fork package (see code below) on R.2.3.1 and ended up with the
same problem. The code from the

Printing integers in R "as is"
Hi,
I am using the following command to print to a file (I omitted the file
details):
cat( paste( paste(orientation, start, end, names,"\n"), paste(start, end,
"exon\n"), sep=""))
where "orientation" and "names" are character vectors and "start" and
"end" are integer vectors.
The problem is that R coerce the integer vectors

Using a number as a name to access a list
Hi
Dumb question time again, for which I apologise.
I have a variable that contains the following numerical text "04010".
This is the name to access a list:
> as.list(KEGGPATHID2NAME)$"04010"
[1] "MAPK signaling pathway"
Marvellous! Except I want to do that when "04010" is assigned to a
variable called path and I can't figure out how to do it!
