[this went to me instead of the list; MM, your list maintainer] I am digging in the wrong hole I guess. Where can I find R /S routines for spatial statistics? Also has anyone made an R link to a GIS package? Anyone out there who works in this area? Thanks Richard E.

In Germany the Unemployment Agency uses a sectioning of the german map that is different from the usual Administrative Boundaries. Some demographic data are available in Administrative Boundaries only, some in Unemployment Boundaries only. I would like to generate estimates in one boundary system of data availabe in the other boundary system, and would appreciate advice concerning the following

Hello R-Group, I am new working with netcdf files and the raster package in R.I am trying to read in a netcdf file using the package "ncdf".I am able to get the lat, lon and parameter I need and can plot using fill.contour.Ultimately, I am trying to create a .asc file to reafd into GIS.I am using the package "raster" to read the parameter.When I read in with

Hi Gurus! I have a job that is to get randomly samples from point-based GIS data (sp called shape GIS files) under the total sum resctricted. For example, I would like to take random smaples under the 1000 persons in each city. The randomly sampled persons should not be over 1000 any case.

Dear All, Has anyone worked with linking R to both ArcView and MapInfo GIS systems? My desire is to capture object selection from GIS and pass to R and to return spatially based statistical model results from R to GIS. If both could simultaneously access the same data file this would be a bonus. My inclination is to put together some routines based on ODBC linking but thought I would seek like

I have no experience with GIS whatsoever. I really know squat about it. I'm currently working on a project to plot locality data for wildlife on a map of Shasta County. This is for a new herpetological club that hopes to track strength of our local herp populations, since it seems evident that in the last 20 years we lost one species of frog and are close to losing another (probably less

Release of revised version of R/GRASS GIS raster and sites data interface. The latest version of the R contributed package "GRASS", release 0.1-6, may be downloaded from CRAN (cran.r-project.org) - contributed packaged section, "Devel" directory, file: GRASS_0.1-6.tar.gz. It may also be downloaded from ftp://reclus.nhh.no/pub/R/GRASS_0.1-6.tar.gz. This version is intended for

Is there an R equivalent to SAS's proc gremove? You would use this procedure to combine the units on an existing map, for example to build a map of Metropolitan Statistical Areas (MSAs) from the [US] counties dataset where the internal boundries surround the MSAs (which are groups of counties) rather than the individual counties. I can imagine the mechanism would be to find and erase the

I have a geodatabase and would like to import it into GRASS, but it is in .mbf. I use mac and linux, and don't have access to access on the machines that I normally use. I do have access to access at school, but I would like to find a way around this if possible. Any thoughts, comments, or suggestions would be welcome. thanks, -- Stephen Sefick Let's not spend our time and resources

If I have a list I can set a sub-element as follows on the command line: people=list() people$tom$hair="brown" people But what if I have a string containing the name of the sub-element that I want to access? subel= "people$tom$hair" get(subel) # returns error assign(subel,"red") # silent but doesn't change list people The attempts above using assign/get

Hello: I would like to superimpose vector polygons (state outlines) from a Shape file on top of a satellite image, imported into a SpatialGridDataFrame from GEOTIFF via gdal_translate and readGDAL. When I plot polygon and point shape files in R, into SpatialPointDataFrame and SpatialPolygonDataFrame, the two feature sets line up geographically, so it seems logical that a SpatialGridDataFrame

Dear Dirk et al, What I've tried is to install libgeos-dev: sudo apt-get install libgeos-dev Which gives me, even after adding the ubuntugis-unstable PPA: E: Unable to locate package libgeos-dev So I'm a little stuck at the moment. I'm trying to install TMAP on R-Studio, which requires a number of packages all of which rely on the libgeos-dev being in place, and I can't seem to

Is there any way to run an R script without running R? As an example, suppose I have a tcl/tk interface that asks for a number (in a GUI) and displays its factorial. Is there a way to invoke this script without invoking R? I'm using R 2.4.1 in GNU/Linux Fedora Core 4. Alberto Monteiro

Hi there, I want to install locfit in R for Windows NT. I have recently downloaded the file locfit.zip from http://www.ci.tuwien.ac.at/R/bin/windows/windows-NT/contrib/ but it doesn't include any explanation on how to do the installation. Have anybody done this? If so I'd really appreciate your help. Cheers, Oscar -- ------------------------------------------------------- Oscar

Dear R Users, I want to test the dimensions of an incoming vector, matrix or array safely and succinctly. Specifically I want to check if the unknown object has exactly 2 dimensions with a specified number of rows and columns. I thought that the following would work: > obj=matrix(1,nrow=3,ncol=5) > identical( dim( obj) , c(3,5) ) [1] FALSE But it doesn't because c(3,5) is numeric

Hello all, I've got a problem with a function in a R package I've developed (MetaLandSim). One of the outputs of my function is the plotting of four images (combining a graph and a map). This plotting is made in a graphical device, with the graph in one side and the map in the other. My function works perfectly fine until it has to plot the map. Then it stops and I get an error.

Hello all, I'm having troubles getting R to load data from GRASS 7. I suspect I have installed something wrong, but can't figure out what. Any suggestions for what I could look for or how to trouble shoot this? Thanks in advance for any help! After having other issues last week, we have upgraded Debian to the testing version. The other problems are solved, but now I can't get

Dear R Community- I am a new user of R. I am using R with GRASS GIS. I would apply svm "on" raster data in GRASS. Basically I have a raster with "areas training" and other three raster (each represents a band of ASTER satellite image). My goal is to classify, according to training areas, the 3 raster. Trying to replicate the guides found on the net, I did the following: #

Besides the primary citation, "Kennedy, W. J. Jr and Gentle, J. E. (1980) Statistical Computing Marcel Dekker." (which is $300 and my library doesn't have it), is there any other documentation on how to take a poly() object and predict "by hand" new data? E.g. What do those coefficients actually mean ("The orthogonal polynomial is summarized by the coefficients, which
