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.

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,

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

RArcInfo Package, get.bnddata()
I am having trouble using get.bnddata() in the RArcInfo package. I
installed the version 0.2 binary of the package for Windows and am using R
1.4.1 on Windows NT 4.0. I have had no problems importing and plotting arc
data with get.arcdata() and plotarc(). plotpal() also works fine. I've
been able to use get.arcdata(), get.labdata(), get.paldata(),

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

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.

Platforms with MSB (Most Significant Byte)
Hi,
I asked some days ago how to guess the o.s. the machine is running. I
found that it is stored in a variable called R_PLATFORM. Now I need a
full list of all the values this variable can have because I need to set
an option depending on the endianness of the platform in which we are
compiling the package.
Anyone can help me? Thanks,

any european maps
Dear all,
I've seen that there are some maps, or at least costlines in R. The oz
package is the map of Autralia and in the fields package there is a US
map and a world map. This world map allows to select smaller sections
such Europe:
library(fields)
world(xlim=c(-10,18),ylim=c(36,60))
However, at this scale the map is quite crude (and several important big
islands are messing).

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

Some questions about R-(D)COM
Hello Thomas,
I am writting to you because I have some questions about R-(D)COM. The
first one is whether it can compiled using the MINGW C compiler, that
is recomended by B. Ripley to compile R under Windows.
The other questions are:
- How can I open/close connections directly from C/C++?
- Do you know about a free Visual Basic compiler?
The final purpose of using R-(D)COM is to create a
