R(D)-COM stat conenctor for ArcGIS
Hi everybody,
I heard about "R(D)-COM Stat connector" for ArcGIS, but i am not
sure what that is. I did a search in the archive but it seems i am
not getting anything back.
can anybody explain me what that is, and where i can find more
info about it? There is any possibility to run R from inside
ArcGIS?
there is more than RArcInfo and Shapefile which can

Maps in R
Is there a way to generate maps in R. Specifically, I have calculated
estimates of intra-regional inequality for US states, and would like to
project that information onto a map.
Thanks,

bootstrap pValue in DClusters
Hello R-List
I use DClusters package (I work in a cancer regestry). I have 2 questions
about it:
1-how is it possible to get back the bootstrap pValue? I mean the pValue of
the calculated statistic with respect of the distribution of this statistic
under the null hypothesis.
2-how is it possible to test an overdispersion in the poisson model? for
choosing a best model I need this mesure of

Problems when plotting (related to RArcInfo)
Hello,
I am using RArcInfo to create some maps but, once I have plotted the map
(using plotarc), I try to add new lines, but the fact is that they are
not plotted.
I have reviewing the code, and if I remove a line, everything works
fine, but I am not sure whether I should do that, because that line
restores the previous 'par' profile.
Here is a portion of the code (from plotarc.R):

RArcInfo:Â can't read arc coverage
Dear all,
> On the advice of Virgilio, I converted my Arc v.8x coverage into v.7x, but

D. Morisette has also reported some 'weird' coverages, which do not
follow the standards. Perhaps you have one of them. Please, take a look
at http://pages.infinit.net/danmo/e00/docs/v7_bin_cover.html

Extrange behaviour of Gcc-3.3
Dear R users,
I have found a quite uncommon behaviour when compiling a library I want
to call from R (avce00, in package RArcInfo).
I define CPL_LSB (-DCPL_LSB is passed to the compiler in the command
line) but it's useless, since #ifdef CPL_LSB ... #endif clauses doesn't
notice that CPL_LSB is defined. I also set -O2.
Any clue? I have tested the library without optimising the code and

Parallelizing spatial computations
Hi,
I have to run lots of simulations based on several spatial scan
statistics. Since the main overhead is due to a call to 'apply' , I
was wondering whether it could be possible to parallelize this "loop".
I know there are a few packages for parallel computing in R but I don't
know whether it's worth trying them. Have anyone used these packages
before?

New package: DCluster
Dear R users,
I am glad to announce the release of a new package for R: DCluster. It
implements a number of methods for the detection of clusters of disease.
It includes methods to test Poisson extra-variation (Chi-square test and
Potthoff-Whittinghill's test), Spatial Autocorrelation (Moran's I and
Geary's c), general clustering (Whittermore's statistic and Tango's

Re: RArcInfo question(basic=T, newbie=T, annoying=T)
Dear Steve,
I'll post your question also to the R-help mailing list since I think
this can help to other RArcInfo users.
As I mentioned in the last release of the package, I have a tutorial
nearly finished. I hope to release it in the next days.

again and know it does. Please, download it again, and sorry for the
inconvenience.

More problems with lattice and postscript
Dear List members,
I am trying to produce some trellis graphics and to save them in a
postscript file but I only get blank files. R behaviour is certainly
strange because I use a loop to generate the graphics (see code below).
When I change the loop variable myself the postscript graphics are OK.
I am using R 1.9.1 (2004-06-21) on Debian GNU/Linux which I try to keep
updated on a daily basis. I

Plan to build Package to use GRASS from R
Hi
Sorry for crossposting, but I think this can be of interest for GRASS and R
users.
I am planning to write a package to make the use of GRASS from R easier. The
idea is to wrap the system call to execute the GRASS command into an R
command of the same name.
e.g:
r.to.vect <- function(..., intern=TRUE, ignore.stderr=FALSE)
{
comm <- paste( "r.to.vect ", ...,

Fitting mixed-effects models with lme with fixed error term variances
Dear R users,
I am writing to you because I have a few question on how to fix
the error term variances in lme in the hope that you could help me. To
my knowledge, the closest possibility is to fix the var-cov structure,
but not the whole var-cov matrix. I found an old thread (a few years
ago) about this, and it seems that the only alternative is to write the
likelihood down and use optim or a

R equiv to proc gremove in maps package
Is there an R equivalent to SAS's proc gremove? You would use this procedure to combine the units on an existing map, for example to build a map of Metropolitan Statistical Areas (MSAs) from the [US] counties dataset where the internal boundries surround the MSAs (which are groups of counties) rather than the individual counties. I can imagine the mechanism would be to find and erase the

Windows R CMD build <pkg> leftovers
A command
R CMD build <pkg>
that fails, e.g., because of C code compilation errors, leaves a
directory %TMPDIR%/Rinst.xxx containing the file R.css. Although R
CMD INSTALL --build cleans up after itself, build does not. A fix is
below. Also, build.in references Rcmd.exe, which I thought was no
longer necessary?

contour plot for non-linear models
Hello all,
I've tried to reproduce the contour plot that appears in the book of
Venables and Ripley, at page 255. Is a F-statistic surface and a
confidence region for the regression parameters of a non-linear model.
It uses the stormer data that are in the MASS package.
I haven't been able to reproduce the plot either in R ( version 1.5 )
and S. It makes the axes and it puts the
