...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?

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 than...

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.

...irectory. Is this correct? An earlier version of rgdal must have allowed this because I have a older script that used to work, but doesn't now. So, as an example, here is what I get today: > shape = readOGR('.', layer='S20_G75_V00_HAASHP10_R00') OGR data source with driver: ESRI Shapefile Source: ".", layer: "S20_G75_V00_HAASHP10_R00" with 169 features and 23 fields Feature type: wkbPolygon with 2 dimensions > writeOGR(shape, '.', layer='temp', driver='ESRI Shapefile', verbose=TRUE) Error in writeOGR(shape, ".", lay...

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

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! ). But, I really don't...

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 f...

Hi, Doing more search i've discovered package RGDAL that can write a geotiff file with projection. I saved a geotiff file in UTM projection and if i read the file back in R and check the projection seems that everything is OK. But if i load the file in ArcGIS (ESRI product) i get the warning that the file is missing spatial reference so it cannot be projected, but it is displayed correctly. I guess somewhere i am doing a mistake when i define the projection in R. My code follows: data.grid <- read.csv(x, header=TRUE) gridded(data.grid) = ~East.m.+North.m...

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

Well Dr. Ripley helped me solve the first problem, next question I need to do some debugging now that the function loads properly into R. I checked the S documentation and to use the C I/O functions you need to include newredef.h, this file doesn't exist in /src/include. How does this work in R? under S3.4 on a dec station i could use fprintf(stdout,..); fflush(stdout); thanks, Nicholas PS

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 Health. --------------...

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

Hi All! As a new useR, I am currently working in R 2.5.1 to produce Ripley's L (the linear version of Ripley's K) for a spatial point dataset (originally a ESRI shapefile). I have coerced the data to a ppp object (because I was originally using 'kest' in the spstat package to produced Ripley's K) but I need to convert my spatial data to a spp object to be able to use 'kfun' in the ads package (this function calculates Ripley's L an...

In R's maptools package, is there a built-in function to test if a given point is "inside" a given polygon on the map? The map was loaded from an ESRI Shapefile. The point's latitude and longitude are known. Thank you! Aleks -- ------------------------ Aleksandr Andreev Fulbright Fellow Graduate School of Management St Petersburg State University
