I want to read data from a number of files into R. Reading individual files one by one requires writing enormous amount of code that will look something like the following. **************** maptools:::dbf.read("wb-01vc.dbf")->dist1 maptools:::dbf.read("wb-02vc.dbf")->dist2 maptools:::dbf.read("wb-03vc.dbf")->dist3

Dear R users, I use R 2.4.0 on an iMac running Mac OS X 10.4.8, with a 2.16GHz Intel Core 2 Duo and 2GB 667 MHz DDR2 SDRAM. > sessionInfo() R version 2.4.0 (2006-10-03) i386-apple-darwin8.8.1 locale: es_ES.UTF-8/es_ES.UTF-8/es_ES.UTF-8/C/es_ES.UTF-8/es_ES.UTF-8 attached base packages: [1] "methods" "stats" "graphics" "grDevices"

Cran task views seems to be a "once-per-session" process -- the first attempt to access views in a (RGui for Windows) session works, but subsequent attempts fail. There is a noticeably long pause before the failing call returns. Example session with two calls to "available.views" follows, but similar effects have been observed with two calls to "install.views" and

Hi, I use Sweave extensively in my consulting work. When submitting reports to the scientists I work with I like to use the citation function to reference any packages I use, to give proper acknowledgement. I noted in the documentation that a citation inherits from bibentry, and indeed, > citr<- citation() > class(citr) [1] "citation" "bibentry" However, following

Revised versions of maptools, a package for reading geographical data from shapefiles, and sp, a package with classes and methods for spatial data handling, have been released on CRAN. They are maptools release 0.5-1 and sp release 0.8-1. The maptools package now depends on sp (>= 0.8), so that users of maptools will need both to update the package itself, and to install the sp package. All

Hi, The following function does work optimize.W<-function(W,k,G,Groups,cph.call,z){ n<-length(Groups) grp.wt<-rep(0,n) for(i in 1:(length(G))){ ind<-Groups == G[i] if(G[i]!=k){ grp.wt[ind]<-W[i] } elsegrp.wt[ind]<-1 } z<-data.frame(cbind(z,grp.wt=grp.wt)) #needed to make the case weights #part of the data

The legacy R spatial infrastructure packages maptools, rgdal and rgeos will be archived by CRAN on Monday, October 16, 2023; rgrass7 has already been replaced by rgrass and will be archived with the retiring packages.

Hi, I am trying to compile a package i am developing on my home computer where i am running Windows NT 4.0 service pack 6. Everything works fine on my other computer at work running windows 98. I am using the cygwin 1.1 bash shell and tolls with the MingW compiler, version 2.95.2-1 installed seperately and first in the path. I have active perl 6.16 as well. Here is the error I get when i run

The third report on the R-spatial evolution project has been published. https://r-spatial.org/r/2023/04/10/evolution3.html It links back to earlier blogs and presentations, and focuses on work that maintainers of R packages and workflows using rgdal, rgeos and maptools need to put in train now before the packages are archived on CRAN. The first changes will occur in June 2023, and the

My sincerest apologies, as this is a very elementary problem, but I have searched through archives and FAQs and on the web, and I am at the end of my own resources. I need to do analysis of a spatial point process occuring with four counties, using spatstat. I've had no trouble importing the shapefiles, but I can't seem to figure out what I need to do in order to use the boundary as an

Dear all, I would like to produce a map with information about the patenting activity in German districts, by coloring districts with different degrees of patenting activity in different colors. I work with the packages maptools, maps and spdep. The map data is read from an external .shp file (+ the corresponding .shx and .dbf files). Plotting a map with the IDs or the patenting indicator itself

Dear R users, I would like to draw map and import it in maptools/spatstat packages. The 'raw data' I have come from a web page (<map>...</map>) and are basically a list of coordinates of a polygon. I would like to know how to import them in R; I checked the maptools packages, but all the examples use existing .dbf files. I just have a (serie of) text file(s) looking like

Hi, I have submitted the package maptools (the file is maptools-0.1a.zip). The archive contains the source ready to compile. I have tested everything on windows 98 and NT and haven't found any major bugs (yet). It should work on lin/unix as well but I don't have easy access to a machine to test it. Of interest might be the functions dbf.read and dbf.write. Also there is a function to

thanks to all the help so far I have code now that works on windows (albeit very clunky) that can read the pertinent info from the shape header and return a list with all the necessary parameters to read info out of the shape file. Now come the big design questions 1) I have considered building a map object, basically a list that would hold the info from the shape file and a data frame as part of
