Hi, I have just put the source code (and a zip file for Window$ users) of package DCluster in my website: http://matheron.estadi.uv.es/~virgil/Rpackages/DCluster/ DCluster is a package that contains routines for the detection of spatial clusters of diseases (Openshaw's GAM, Besag and Newell, Kulldorff and Nagarwalla, Stone's Test and others). A full description can be found here:

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

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

Hi, A new release of RArcInfo is out, together with a draft of the tutorial. You can get both from http://matheron.estadi.uv.es/~virgil/Rpackages/RArcInfo Windows binaries are also available and package source can also be downloaded from CRAN. I 'd like to encourage users of the package to read the tutorial and report ideas. Besides, I would like to keep a web page on works where RArcInfo is

Dear all, > On the advice of Virgilio, I converted my Arc v.8x coverage into v.7x, but > that made no difference (ESRI documenation says they should be the same anyway). 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 Anyway,

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. > I have downloaded an .e00 file of 2000 Census Tracts for the southern US > State of Georgia, and I'm wondering which steps I need to go

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):

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

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

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, Virgilio Gómez Rubio Dpto. Estadística e

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, Nirmala

Hi, A new release of RArcInfo is avaialable from CRAN and http://matheron.uv.es/~virgil/Rpackages/RArcInfo/ The changes made are: *V 0.4-2 - 'index' argument added to plotarc to select the arcs to plot. - 'index' argument added to plotpal to select the polygons to plot. - New function 'get.nb', which, given a set of polygons, returns the neighbouring polygons of

Hi, As Frank M. Howell noticed (and probably other users), the Windows binaries for DCluster I put in my web page are not working... I have compiled the source code again and know it does. Please, download it again, and sorry for the inconvenience. The URL is http://matheron.uv.es/~virgil/Rpackages/DCluster DCluster is a package that implements some methods for the detection of spatial

Dear R experts, Attached you can find the expression of a loglikelihood function which I would like to maximize in R. So far, I have done maximization with the combined use of the mathematical programming language AMPL (www.ampl.com) and the solver SNOPT (http://www.sbsi-sol-optimize.com/manuals/SNOPT%20Manual.pdf). With these tools, maximization is carried out in a few seconds. I wonder if that

Dear R users, I use the glm() function to fit a generalized linear model with gamma distribution function and log link. I have read in the help page that the default method used by R is "glm.fit" (iteratively reweighted least squares, IWLS). Is it possible to use maximum likelihood method?

Hi the list, I have a problem of memory space while running step() function: Error: cannot allocate vector of size 50.9 Mb I've tried with: > memory.size(max = FALSE) [1] 803.4714 #which should be the amount of memory currently in use > memory.limit(size = NA) [1] 1015.480 #which should be the memory size > memory.size(max = TRUE) [1] 997.75 #which should be the

Dears I am searching information about how to use raw data, when it is used, didn't find to much information on R help.

Hi, I have tried to install the R package Rcplex on windows xp without success. I have only cplex_studio124.win-x86-32 version. I have modified the makevars.win file as indicated in the installation guide ( http://cran.r-project.org/web/packages/Rcplex/INSTALL ), then I zipped the whole folder to order an installation from a zipped file (utils :menuInstallLocal()) The message I had is file

Hi, I am working with lists whose terms are lists whose terms are lists. Although the real ones contain locuslink identifiers and GO annotations (I work with the Bioconductor GO) package, I have prepared an simplified example of what I have and what I would like to do with it: Imagine I have a list such as:
