options("digits") and print.default()
Hello everyone,
I use latex() (Hmisc) for report generation and thus have been affected by
the problem with rounding decimals described, for example, in this post:
http://thread.gmane.org/gmane.comp.lang.r.general/73287/focus=73287
In short, numbers often are printed with 15 or so decimals even if there
far less significant digits. The problem has been confirmed by Frank
Harrell and Thomas

Using multicore with an open pdf device results in corrupt pdf (PR#14186)
The attached code produces corrupted pdfs (test2.pdf, test4.pdf and
test5.pdf). The resulting pdf depends on how many cores are available on
the machine.
I don't see why there should be any difference between the pdfs (exept for
the timestamp). Doing many operations involving mclapply can increase the
size of the resulting pdf by ten times!
Thank you for checking this.

Calculation of Covariance Matrix Calculation
Hi,
Excuse me for asking this silly question. But I really couldn't understand
why cov() and ccov() don't work for my calculation of covariance matrix.

[1,] 1 3 5 7

Rcmdr package dependencies
Dear r-devel members,
My Rcmdr package "depends" on several other packages (tcltk, grDevices,
utils, and car) and "suggests" a number of others (abind, aplpack,
colorspace, effects, foreign, grid, Hmisc, lattice, leaps, lmtest, MASS,
mgcv, multcomp, nlme, nnet, relimp, rgl, and RODBC). The reason for the
distinction is that I don't want all of these packages to load when

Results of MCD estimators in MASS and rrcov
Hi!
I tested two different implementations of the robust MCD estimator:
cov.mcd from the MASS package and
covMcd from the rrcov package.
Tests were done on the hbk dataset included in the rrcov package.
Unfortunately I get quite differing results -- so the question is whether
this differences are justified or an error on my side or a bug?
Here is, what I did:

Help installing R commander in Fedora 13...
I did a standard install of R on Fedora 13 using yum as root, which I

any of the menu "Packages" is not working.

Fast Kendall's Tau
Hello.
Has any further action been taken regarding implementing David Simcha's fast Kendall tau code (now found in the package pcaPP as cor.fk) into R-base? It is literally hundreds of times faster, although I am uncertain as to whether he wrote code for testing the significance of the parameter. The last mention I have seen of this was in 2010

Package rrcov, functions PcaCov, PcaHubert, PcaGrid
Hello,
I'm using the R-2.13.1 version in Windows and I'm trying to do a robust Pca

The following error occurs:

The same error occurs with the other functions. What does this mean and how

140 packages in R Commander!!
Dear List
I just downloaded and installed R 2.12.0 and then installed R Commander .
First it got RCmdr and Car, and then suggested for other packages for
utilizing the full functionality- I clicked yes!
I got 140 packages installed!!! Cran Mirror was UCLA...
Here is the list.
Is this intentional- I can see some packages like snow and multicore which
are desirable but quite optional.(see list

Problems with subset, droplevels and lm: variable lengths differ
[Env: R 2.14.2 / Win Xp]
In the script below, I want to select some variables from

The checks I run on my new data frame Oslo look OK, but I when I try to

Caras de Chernoff
Hola a todos, estoy jugando con las caras de Chernoff de la librería aplpack. La
verdad que se consiguen efectos curiosos. Me preguntaba si me recomendáis alguna
otra implementación para R de estas caras. Y si existe alguna forma de poderlas
usar para más de 15 variables (si no me equivoco así es como viene implementada
la función faces)

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 my R package still compiling with the O2 flag?
When I install an R package with cpp codes such as rrcov via CRAN (under
R 3.1.1, using no Makevars file and under Ubuntu 14.04 using GCC 4.8),
the cpp code is compiled with the -o3 flag (in fact, looking at the
Makeconf file this seem to again be the default since R 3.1.1) But when
I install my own package via CRAN it is compiled with the -o2 flag.
My questions are what is causing my

How do you prove usefulness of a feature?
Do you have an example of a feature that has been added after proving to be
useful in the package space first?
Thank you,
