package test failed on Solaris x86 -- help needed for debugging
Dear R developers,
we have currently a 'mysterious' test problem with one package that
successfully passed the tests on all platforms, with the only exception
of Solaris x86 where obviously one of our help examples breaks the CRAN
test.
As we don't own such a machine I want to ask about a possibility to run
a few tests on such a system:

optim: why is REPORT not used in SANN?
Hello,
I wonder why the control parameter REPORT is not supported by method
SANN. Looking into optim.c I found an internal constant:
#define STEPS 100
... and decreasing this to 10 helped me fine-tuning the annealing
parameters in an actual problem.
Is there any reason why not passing nREPORT to samin and setting
something like:
STEPS = nREPORT / tmax

nlminb: names of parameter vector not passed to objective function
Dear R developers,
I tried to use nlminb instead of optim for a current problem (fitting
parameters of a differential equation model). The PORT algorithm
converged much better than any of optim's methods and the identified
parameters are plausible. However, it took me a while before spotting
the reason of a technical problem that nlminb, in contrast to optim,
does not pass names of the

linking to package directories broken in R >= 2.10 beta

This directory is linked from the docs (e.g. in inst/doc/index.html):

package simecol uploaded to CRAN
Dear useRs,
a new and completely re-worked version of the "simecol" package
SIMulatiion of ECOLogical (and other) dynamic systems
is now available on CRAN. Compared to the S3 based 0.2-x versions an
improved object model using S4 classes was employed. Please ask me for
assistance in case of incompatibility.
Comments are welcome, Thomas Petzoldt

vignette index not linked into HTML help system for package
Dear R developers,
I observed that the html help page index entry "Read overview or browse
directory" for package vignettes is missing in recent R-devel.
This happened on two independent computers (WinXP Prof. SP3, German)
with R-devel compiled from sources svn rev. 48125 resp. 48128
It's the same for my own and also for more prominent packages as well
(e.g. grid).

experiments with slot functions and possible problems NOTE
Hello,
first of all, thanks to LT for \pkg{codeutils}. I agree that it is
indeed very useful to identify errors and also to encourage re-thinking
past solutions. My problem:
I want to compare different sets of related sub-functions which should
be used alternatively by the same top-level function. Sets of related
functions should be bound together (as lists) and the workspace should
be as clean

package check note: no visible global function definition (in functions using Tcl/Tk)
Hello,
when testing packages under R version 2.6.0 Under development

get numerous "possible problem notes" for different (own and other
contributed) packages containing Tcl/Tk code, e.g.:

External signal in ODE written in C (using deSolve and approx1?)
Dear list
The deSolve package allows you to specify the model code in C or Fortran.
Thanks to the excellent vignette this works fine. However I have not yet
managed to use forcing functions in C code.
In pure R code this works very well with approxfun() specified outside the
model:

New package test results available
We've added a column at
http://cran.r-project.org/web/checks/check_summary.html
of test results using the Sun Studio compiler: it is intended that
these will be updated weekly.
The Sun Studio compiler is that used on Solaris: these runs were on
the Linux version. All the other platforms are using gcc 4, so this
provides an opportunity for checking for use of gcc-specific features

why is \alias{anRpackage} not mandatory?
Dear R developers,
if one uses package.skeleton() to create a new package, then a file
anRpackage.Rd with the following entries is prepared:
\name{anRpackage-package}
\alias{anRpackage-package}
\alias{anRpackage}
\docType{package}
Packages created this way have a definite entry or overview page, so:
?anRpackage
gives new users of a certain package a pointer where to start reading.

silent option in nested calls to try()
Hello,
is it *really intentional* that the "silent" option of try() does only
apply to the outer call in nested try constructs? I would assume that a
silent try() should suppress all error messages regardless where they
occur, even if they are already handled with other try()'s.
The error message itself should be (and is in both cases) reported by
the return value of try().

pdf() device uses fonts to represent points - data alteration?
Hello all,
I discovered that the pdf device uses fonts to represent "points"
symbols (as in plot(...,type="p",...) ). Namely it uses ZapfDingbats
with symbol U+25cf. This can lead to problems when the font is not
available, or available in another version (such as points being
replaced by other symbols, or worst: slightly displaced).
Furthermore, it also causes

plot.hclust with lots of objects
Dear all,
The default plotting method for hclust trees looks just fine for few
objects like in the example dataset. But when it comes to many
features (eg some 1000 and more - I'm trying to visualize clustered
microarray data) it renders a tree, that one cannot inspect, because
of overlapping text and lines. My question is, is there a way or a
plotting parameter for plotting a tree which is

odesolve dynload example
Hello R Developers,
This is my first foray into using c-code with R, so please forgive my
foolishness.
I had a look at the archives and did not find anything on this, so
hopefully I am not doubling up.
I have tried to use R cmd to create an object file from the odesolve

I am using windows and have just installed rtools, and have the latest
version of stable R (2..7.2).

V2.9.0 changes [Sec=Unclassified]
Hi all,
Prefix: I am a frustrated Java coder in R.
I am coding a medium sized ecosystem modelling program in R. I have changed to using S4 objects and it has cost me an order of magnitude in execution speed over the functional model. I cannot afford this penalty and have found that it is the result of all the passing-by-value of objects.
I see that you can now safely inherit from

R-2.6.0 package check problems
Hello
One of my packages, untb_1.3-2, passes R CMD check under
MacOSX (and apparently the systems used in the package check
summary page on CRAN) but fails with the following message on
R-2.6.0.tgz compiled last night on my (home) linux box. I hasten
to add that I have never seen this error before on home-compiled
pre-releases of R-2.6.0.
Can anyone help me understand what is going on?
