R CMD check: problems possibly from mapply?
Dear expeRts,
I am trying to wrap up a package "utilities" (for my internal use). After
adding a function datNAtreat that uses mapply, R CMD check gives WARNINGs
for "S3 generic/method consistency", "checking replacement functions"
and?"checking foreign function calls", all of which are accompanied by the
following error message:

hierarchical partitioning
Hello,
I would like to know what it means, when the hier.part's output has a data
frame of a negative independent contribution for variables (?IJ) and how
this can be caused.
Thank you very much.

Method for $
Dear R experts,
I have defined a class "myclass" and would like the slots to be extractable
not only by "@" but also by "$". I now try to write a method for "$" that
simply executes the request object at slotname, whenever someone calls
object$slotname for any object of class "myclass".
I don't manage to find out how I can provide this

Question regarding lu in package Matrix
Dear R-helpers,
I have a question regarding LU-decomposition with function lu in package
Matrix. The following simple example confuses me: Why is as.matrix(elu$U)
not an upper triangular matrix?
u3 <-
matrix(c(1,1,1,1,1,1,-1,1,0,0,0,0,0,-1,1,0,0,0,-1,0,1,0,0,0,0,0,-1,1,0,0),5,6,byrow=T)
elu <- expand(lu(Matrix(u3,sparse=F)))

Major update to package relimpo: Version 2.0
Dear userRs,
Version 2.0 of package relaimpo is on CRAN (and on my homepage with an
additional metric for non-US users). It contains several major improvements:
- usage of factors
- incorporation of interactions (for metric lmg only)
- incorporation of observation weights
- application to data from complex surveys
- processing of multiply imputed data
The latter two points are somewhat

Problem tracking down an R CMD check syntax error
Dear all,
I am stuck with tracking down an error I get from R CMD check (Windows, R 2.4.0, same error for R 2.2.1): when running R CMD check over a modified version of package relaimpo, I get the following output in install.out:

Bug in str or issue with class management in my package?
Dear developeRs,
with R 2.4.1 (and also 2.4.0), the function str() fails on objects of class
relimplmbooteval, if there are unused slots, which is very often the case. I
am not sure whether this is a bug in str() or a correct behavior of str()
that unmasks some sloppiness in my usage of S4 classes (that I am not aware
of)?

Wishlist: install.packages to look for the newest version of a package (PR#13851)
Full_Name: Ulrike Groemping
Version: 2.9.0 (and older)
OS: Windows
Submission from: (NULL) (84.190.173.190)
When using an older version of R, packages are not found although they are
available for newer versions of R and do work when installed with the old
version. For example, installing DoE.base on R 2.8.1 installs version 0.2, while
CRAN is at version 0.4-1 currently. It would be nice if the

Bug in function boxplot's axis labeling
Dear developeRs,
I appreciate that boxplot now labels the axes with variable names per
default. However, with argument "horizontal=TRUE" (which I always use),
the default axis labels are mixed up, as can e.g. be seen with
require(boot)
boxplot(time ~ poison, poisons, horizontal=TRUE)
The correct labels would be obtained by
boxplot(time ~ poison, poisons, horizontal=TRUE,

Issues with TMPDIR/TEMP/TMP? Failure of R CMD check under Windows 7
Dear helpeRs,
on my Windows 7 laptop, I have problems getting R CMD check to work. I
believe it did work completely before, but I am not sure.
Yesterday it almost worked, except for the tests: These were aborted
because of a complaint that the temporary directory wasn't available. I
played with windows environment variables for the temporary directory,
but that didn't solve it.

Importing function that is previously imported by other package
Dear developeRs,
I encounter the following problem: in the current version of my package
FrF2, certain calls to a functioni do not work when package combinat is
loaded, because function combn from combinat masks the function from
utils that my package uses.
I tried to solve this issue by importing function combn into the
namespace of FrF2; I don't need to export it, I just want to use it

Two R sessions on multicore computer seem to inhibit each other ?
Dear R-helpers,
I am puzzled by the following observation:
On my home dual core Windows desktop computer, I am used to running two R
sessions in parallel. These do very well in using the full CPU of the
computer (half each) and don't seem to slow each other down.
Today I have started some large computation effort in one of our university
labs, and I intended to go for two R sessions per

I've been struggling with the new regulations regarding modifications to

Problem with correct usage of formula environment
Dear all,
I am working on a function formula.design that should automatically generate
reasonable lm formulae for a number of different designs. All works well as
long as all variables used are columns of the design data frame. For one
function, I would like to incorporate a dummy variable for center points
that is not a column of the design. Without this function, it would work

Wishlist: install.packages to look for the newest version (PR#13853)
Uwe,
I am talking binaries and Windows. I was not thinking of building
binaries for old versions, but of looking in the new version
repositories first, whether there is a binary that is said to be valid
for the older version. Wouldn't it be possible to have the process look
up a table of a newer R version for compatible binaries ?
I got stuck with R 2-8.1 (which is not that old and should

Wishlist: install.packages to look for the newest version (PR#13852)
Ulrike,
if you install from source, you always get the most recent version of
the package given it does not depend on a newer version of R.
If you want a binary package, you also get the newest version - that was
newest at the time we stopped building binaries for that version of R.
We (or better I if we only talk about Windows, but similar for all other
platforms) cannot build for each R

Sourcing files with Umlaut in path no longer works
Dear helpeRs,
on my new machine - Windows 7 64Bit, R 2.15-2, I can no longer source
files for which the path contains the o-Umlaut (?). As a historical
burden, my username is Gr?mping and contains that Umlaut (I wouldn't
have chosen it now, but decided to keep it for easy transfer). I have
had the difficulty that I couldn't use the R CMD tools on files with

Cannot activate chm help in R 2.10
Dear all,
I just tried to be fast for once, installed R 2.10 and also newly installed
all previously-installed packages. However, now all my help files are text

help pages. What can I do to re-activate chm-help? chm-help does not work
for anything, not even base functionality.

Time delay function or plot animation
Dear R-help crowd,
is it possible to specify a time delay for plotting the points in a curve? I
would like to make the plotting process slow enough to show the development
of the graph, and therefore I am looking either for the possibility within
the plot function to specify a plotting speed or (if that doesn't exist) for
a function like "pause" or "wait" that allows
