How do I change the editor in R command window?
Dear R-help,
I have started using R on my Linux box (Debian), and I have some
problems with setting the editor/keyboard for R. The
For instance, arrow-up gives "^[[A", and delete gives "^H". I have a
Norwegian keyboard, but that doesn't cause any
problems for editors like emacs. Could you advice me on how I can set
the editor for R right? I have tried

using the netCDF.zip package in Windows (XP).
Dear R-help,
I have a question relating to the netCDF package for R in the Windows
environment. I
have used this package in the Linux version with no problem, and the
Windows version
of R installed the package without problems. But there are problems when
I try to read a

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?
Cheers,

Random Beta variates
I have been trying to use the rbeta() function to generate random beta
variates with a particular mean and standard deviaiton for some simulation
problems
I am working on, however I am unsure of the relationship between the
parameters shape1 and shape2 and the mean and standard deviation of the
beta
distribution. I am guessing that there is a formula for this, but I am
unsure what it is. Can

y axis on hist
Hi:
The y axis on the hist function seems to set its limits oddly.
sometimes, it covers the full range of the data and sometimes it stops
one major tick short. I have had this behavior with a variety of data
sets, and it can easily be reproduced by just running the following
several times:
hist(rnorm(100000))
I have tried explicitly setting ylim to the range of values produced by
rnorm

nearest neighbour interpolation
Dear Help List,
My name is Matt Oliver. I have been using R for about a year and find it very
helpful. However, I have a need for a function that I cannot find. I am not very
good at programming so I thought I would ask the group.
I have an irregular grid of data (x = Longitude, y = Latitude). Each pair of my x,y
has a categorical value. Obviously linear or any other numerically based

basic question
Dear R users,
Up to now, I only used precompiled packages. As I am working on vegetation
ecology, I would be interested in using a package not stored by CRAN called
labdsv_0.9-1.tar.gz and developped by Dave Roberts at the National Center
for Ecological Analysis and Synthesis (unfortunately I did not find any
corresponding .zip file).
Although I tried to follow the proposed guidelines to

Sweave in packages
Dear R folks,
One of the fantastic new tools in R is `Sweave'. I have tested it so much that I
know it works and produces fine documentation, and with (GNU) Emacs/ESS it is
nice to work with, too. I started to have a look at including some Swoven (is
that a strong verb?) documentation with my R package, but it seems that there is
no model to copy among those packages that I have installed in

installing labDSV library
I am trying to install labDSV from http://labdsv.nr.usu.edu/ into
R-Windows 1.5.0.
It only comes as a TAR file which extracts into folders that seem to match
those for other libraries DATA, MAN, R and SRC. I have manually copied
these folders into a folder called labDSV under the Library directory
under R.
However when I load the library I get a message that the library contains
no R code.

REading the netCDF format into R
Hi!
I have been coding a C-program which will read data from the
netCDF format (a commonly used file format in the geophysical research
community: see Unidata's URL for explanation:
http://www.unidata.ucar.edu/packages/netcdf/), and have got to the point
where I don't know what the error message mean. The C-program is called
nc2r.c.
When compiling the code, I get a number of warnings,

isoMDS
Dear List:
I have a question regarding an MDS procedure that I am accustomed to
using. I have searched around the archives a bit and the help doc and
still need a little assistance. The package isoMDS is what I need to
perform the non-metric scaling, but I am working with similarity
matrices, not dissimilarities. The question may end up being resolved
simply.
Here is a bit of substantive

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

RE: new packages: geepack and KMsurv
I downloaded geepack from your site and installed it from the zip file.
However, although it appears under my library directory, I could not load

indicator value in labdsv
Hi,
I'm trying to find out what threshold of indicator value in labadsv should be
used to accept a specie as an indicator one? So far I assumed that indval=0.5
is high enough to avoid any mistakes but it was based only in my intuition.
I'd be greatful for any advise
best regards

RPM of R-1.2.1 for RH 7?
There does not seem to be a RPM for Red Hat 7 of version 1.2.1.
What should I do? I have a new computer with RH7.
I''m willing to try to make one from the SRPM, but I''ve never done
that before, and I don''t want to go to the trouble if someone
else is already planning to do it soon.
Likewise, I could install it from the tgz file. (I just did that

R.xpm?
I use AfterStep on Linux. I made an R.xpm file (attached)
and put this icon in the "wharf". To invoke R I click on the R icon.
I did not find an offical R.xpm, and so I am submitting this one
for your collective consideration....
The idea behind the icon is that it looks like a scatterplot, which is
"statistical". My main beefs with my R.xpm are that it doesn't have a

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
