similar to: ESRI Shape reader

Hi, I am working on a library of map functions for R and I have started with code to read shapefiles (the format is not great but it is ubiquitous). I am not a windows person, but where I am working I don't have access to any UNIX machines easily. So here's the problem I wrote C code to read the information out of the shapefile header and I compiled it using the script given in Ripley and

Dear R user, I am running R under Windows 2000. I am looking for a routine for importing - shape files (ESRI) into R - dbase files (FOXPRO) into R and I am looking for time-space models for description and prediction of Bernoulli-, Binomial- and Poissonvaraibles. Thank's a lot for a reply. Sincerely yours, Ekkehardt Altpeter Swiss Federal Office of Public

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

Is it safe to call Rprintf and REprintf from a background thread? I'm working on a package that makes calls to fprintf(stderr, ...) on a background thread when errors happen, but when I run R CMD check, it says: Compiled code should not call entry points which might terminate R nor write to stdout/stderr instead of to the console, nor the system RNG. Is it safe to replace these calls

Dear R-devel community, There appears to be an inconsistency in R C API about the exceptions that can be raised from C code. Mapping of R C funs to corresponding R functions is as follows. error -> stop warning -> warning REprintf -> message Rprintf -> cat Rprint/cat is of course not an exception, I listed it just for completeness. The inconsistency I would like to report is

Thank you Luke for prompt reply. Is it possible then to request a new function to R C API "message" that would equivalent to R "message" function? Similarly as we now have C "warning" and C "error" functions. Best, Jan On Sun, Sep 15, 2019 at 5:25 PM Tierney, Luke <luke-tierney at uiowa.edu> wrote: > > On Sun, 15 Sep 2019, Jan Gorecki wrote:

I have the following contrived code in package format. On Solaris and Mac OS X, code runs just fine. On Windows, it crashes the R environment with the "Send Bug Report" dialog. I tried R 1.8.1 (Win2K) and R 1.9 (WinXP) binaries with the same result. PCs otherwise appear properly configured for creating R packages. Anything blatantly wrong? Suggestions?

Does Mapstraction support ESRI (arcwebservices.com)? Thanks, - Michael

I just uploaded two packages to CRAN. shapefiles_0.1.tar.gz - functions to read and write ESRI shapefiles (including dbfs) emme2_0.1.tar.gz - functions to read binary data from an EMME/2 databank data (EMME/2 is a transportation modeling program) Please let me know if you find any bugs or have some suggestions. Thanks. Regards, Benjamin Stabler Transportation Planning Analysis Unit Oregon

Did not hear from anyone on this, so maybe we are the only ESRI users who got bit, but this turned out to be an issue with oplocks. Disabling oplocks on the server eliminated the problem.

Sorry, I did not make my question clear. Since I have a point theme with many points, some of them may clump together. the problems here are: 1. how to find clumps in a point theme? 2. the convex-hull extension I found only deal with all the points in a theme at each time? how to make each convex hull around each point clump automatically? Thanks. Xiaohua On 5/12/06, Bob Booth <bbooth

We just upgraded our samba server from 3.0.14 to 3.0.21a and have discovered a subtle but very painful problem. Users of ESRI ArcMap (on fully patched Windows XP clients) are unable to read complex layered file data. Arcmap works fine with 3.0.14, it works fine with the data on a windows share, and it works fine when I set up a server to run the version of samba shipping with Solaris 9 (3.0.2! ).

Hello- Does anyone know if R can read in ESRI file geodatabase feature classes, directly from the file geodatabase? I currently have to export the data out of Arc, to a csv file, then read the csv file. I'd like to bypass this step and read directly from the file geodatabase. Thanks for your help. -al

Hi all, who knows how to get an ESRI Shapefile for the NUTS-2 Regions of the enlarged European Union? Particularly I want to draw maps of Germany, Poland, Czech Republik, Hungary and Austria. I've found Shapefiles for the US, Russia and other countries elsewhere in the web, but for Europe it seems really difficult. With many thanks for any hint Albrecht

Thanks - I'll find another way to send messages to the main thread for printing. -Winston On Tue, Nov 21, 2017 at 12:42 PM, <luke-tierney at uiowa.edu> wrote: > On Tue, 21 Nov 2017, Winston Chang wrote: > >> Is it safe to call Rprintf and REprintf from a background thread?

Hello, I have an ESRI ArGis geo database directory which I would like to convert to geojson or a shape file (or anything else that I can read into R). Unfortunately that does not work out of the box with rgdal, because it does not come with the fileGDB or openfileGDB driver. I could successfully install gdal and the fileGDB driver/extension, but it seems that i can use gdal only to convert the

Dear All, I'v tried to read in data in numerous ways including:- Spain10km<-data.frame(readAsciiGrid("F://RMap//sp10kpointid1.aux")) Error in readAsciiGrid("F://RMap//sp10kpointid1.aux") : object 'cellsize' not found In addition: Warning message: In readLines(t, n = 6) : incomplete final line found on 'F://RMap//sp10kpointid1.aux'

How much of a resource hog is a PDC? My understanding is that authentication is done vs a BDC if available. I configured my new file server as the domain PDC because I figured it would already have to run samba. I have two other machines configured as BDCs to serve as logon servers. I'm looking for opinions on whether I'm asking for performance problems by making my file server the

Hello all, I am getting into trouble when trying to do standard I/O from a C function called within R environment. This function is written in a small C library that is loaded whith dyn.load() and called in R via the .C() interface. I need to debug the C code using a text file for some logs, and also to speed up its result visualization by creating images on the fly using the GD library. Both
