step() in sink() and Sweave()
Dear developers,
I just noticed that step() function currently prints the current model
using message(), but the resulting model using print(). The relevant
commands within the step() body are:
if (trace) message("Start: AIC=", format(round(bAIC, 2)), "\n",
cut.string(deparse(as.vector(formula(fit)))), "\n")
(with example() output:)
Start: AIC=190.69

Canberra dist and double zeros
Canberra distance is defined in function `dist' (standard library `mva') as
sum(|x_i - y_i| / |x_i + y_i|)
Obviously this is undefined for cases where both x_i and y_i are zeros. Since
double zeros are common in many data sets, this is a nuisance. In our field
(from which the distance is coming), it is customary to remove double zeros:
contribution to distance is zero when both x_i

problem with vignettes when S4 classes in packages overlap
( A similar problem is also reported by Sebastian P. Luque with
library(maptools)
library(trip)
in the vignette as below ).
I am writing a vignette which loads RMySQL and RPostgreSQL. This
produces the warning:
Loading required package: DBI

Why should package.skeleton() fail R CMD check?
I find it a bit peculiar that a package skeleton created with a utils
function package.skeleton() fails subsequent R CMD check. I do
understand that the function is intended to produce only a skeleton that
should be edited by the package author. I think that it would be
justified to say that the skeleton *should* fail the test. However, I
have two arguments against intentional failure:

MDS with missing data?
Hello
I will be applying MDS (actually Isomap) to make a
psychological
"concept map" of the similarities between N concepts.
I would like to scale to a large number of concepts,
however, the
resulting N*(N-1) pairwise similarities is prohibitive
for a user survey.
I'm thinking of giving people random subsets of the
pairwise
similarities.
Does anyone have recommendations for this

MacOS X: update.packages(type="mac.binary") fails (PR#7836)
Message 2 of today: it works now.
After re-installing R.app from the same R-2.1.0.dmg file, and
fixInNamespace'ing(*) install.packages(), I managed to update 23
outdated packages from CRAN binaries for MacOS X. What I did was to:
1. change call to .install.macbinaries() into call to install.binaries()
in install.packages(). install.binaries() is a function defined

Sweave, lty = 3 line incorect in pdf output
I'm having a problem with dotted lines (lty = 3) in the pdf output
in documents generated with Sweave. In the displayed pdf, the
dotted line does not show up and in the printed output, it is
there but does not seem to respect the lwd argument, for example, it
is very faint despite using lwd = 3. The dotted line is correct
in a quartz window and if I save the Quartz window to a pdf

Hi,
I'd like to perform Dufrene-Legendre Indicator Species Analysis for
a multivariate regression tree. However I have problems with arguments
of duleg(veg,class,numitr=1000)function. How to obtain a vector of
numeric class memberships for samples, or a classification object

Shy Suggestion?
The R-exts manual says about 'Suggests' field in package DESCRIPTION:
"The optional `Suggests' field uses the same syntax as `Depends' and
lists packages that are not necessarily needed."
However, this seems to be a suggestion you cannot refuse. If you suggest
packages:
(a line from DESCRIPTION):
Suggests: MASS, ellipse, rgl, mgcv, akima, lattice

Plot of Canonical Correlation Analysis
Dear all,
I didn't find any graphical solution in the package "mva" to plot the
canonical scores from a CCA (canonical correlation analysis).
Does anybody knows how to plot or has anybody already programmed :
- the map of the canonical scores,
- the graph of the canonical weights,
- the correlation circle i.e. the canonical loadings ?
Thank you for help ...

rgl on Mac OS
Hi,
It seems like a number of people on this list can install rgl but have
problem loading it. I found myself in the same situation too.
I have tried the workaround of removing /usr/X11R6/lib from
DYLD_LIBRARY_PATH, but it doesn't seem to work for me, I am still getting
the same error (that everyone else seems to get). Can anyone give me some
ideas on what else to try?
I have Mac OS 10.3.5,

unknown decorana error returned (vegan package)
Hi
After trying a simple decorana analysis (from the vegan package) on a simple
data frame which contains no NA's the following error was returned:
> tt_decorana(covN)
Error in decorana(covN) : NA/NaN/Inf in foreign function call (arg 1)
Have any vegan users come across this error and know what can be done about it?

invalid 'mode' of argument?
Dear Colleagues,
As a novice I was trying to calculate Shannon diversity index using
diversity function in vegan package and kept having same error message.
Error in sum(..., na.rm = na.rm) : invalid 'mode' of argument
My dataset is from microarray and have abundant missing values, so I
tried labeling them as NA and 0, but still same error message.
Shannon index is negative

results from sammon()
Dear all,
I'm trying to get a two dimensional embedding of some data using different
meythods, among which princomp(), cmds(), sammon() and isoMDS(). I have a
problem with sammon() because the coordinates I get are all equal to NA.
What does it mean? Why the method fails in finding the coordinates? Can I do
anything to get some meaningful results?
Thank you very much

How to circumvent negative eigenvalues in the capscale function
Dear All
I am trying to do a partial canonical analysis of principal coordinates
using Bray-Curtis distances. The capscale addin to R appears to be the only
way of doing it, however, when I try and calculate a Bray-Curtis distance
matrix either using Capscale or Vegedist (capscale I understand uses
Vegedist anyway to calculate its distance matrix), R uses up all available
memory on the computer,
