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 solv...

Hi Sorry for crossposting, but I think this can be of interest for GRASS and R users. I am planning to write a package to make the use of GRASS from R easier. The idea is to wrap the system call to execute the GRASS command into an R command of the same name. e.g: r.to.vect <- function(..., intern=TRUE, ignore.stderr=FALSE) { comm <- paste( "r.to.vect...

I am trying to compile the r.stream* set of addons. Ubuntu 9.10 64 bit I have installed the grass packages from the repositories I have also compiled grass 6.5 from source. I have taken the r.stream* from the addons svn and placed the sources in the grass source tree - in the raster file I run make distclean then navigate to the raster/r.stream* file run make and get this error message: ~/sour...

Dear List, I am realtively inexperienced so i apologise in advance and ask for understanding in the simplicity of my question: I have data on the amount of grass per km in a cell ( of which i have lots) "grass" and for each cell i have x/y coordinates - required due to spatial autocorrelation Cells can be classfied in a hierarchical nature into AREAS and STATES i.e Cell 1, Cell 2, Cell 3 are all in AREA "A" where as Cell 4,5 and 6 ar...

Hi, Does anyone use spgrass6 with GRASS 7 and R? The documentation for spgrass6 states it is for GRASS6+, and if I recall correctly I saw Dr. Bivand mention that it works well with GRASS7. (There were some threads from 2009 where spgrass6 wasn't working with GRASS7 yet, but I assumed that information was out of date.)...

Hi all, I have a data frame with sequences of x and y from a map. I would like to know it both ways: 1. How to make a matrix from that; 2. how to make a data frame of all points in a map. Probably it is a silly question, but please tell me where to read about it or tell me how to do it. Miha Staut

Dear list, since I have installed GRASS_0.1-8.tar.gz (devel) with R 1.4.1 on RedHat7.1 Linux I get the following message when I want to save the workspace image: -------------------------------------------------- Save workspace image?

Hi, everybody! i created a imagem by kriging using geoR package. I imported points from GRASS("zn", after converted to geodata "zn_geo"), the border "zn_border" and a raster mask. Then i interpolated the points by kriging and created a raster image. Now, i need export this image back to GRASS to use it in the module r.mapcalc. I can't do it. I tried use wri...

Dear list, I have a problem to install the GRASS_0.1-4.tar.gz on RedHat7.1 Linux. The gmake5 is missing. But I am not quite sure what it is? Is it a gnu version of MAKE? I could not locate it on my system and I do not know what is really meant. Any experience? I get the following message: ----------------------------------------------------...

Hi, I just imported two raster maps into R using the SPGRASS6 package, one containing elevation data and the other containing an erosion index: Kar_inc <-readRAST6("Incis_Kar", plugin=FALSE) Kar_dem <- readRAST6("DEM_Kar", plugin=FALSE) I just wanted to make a xy plot of erosion parameter vs elevation. How does this work? I don...

Hi all, In my version of the R package GRASS (pre-4) I only manage to export an R object to GRASS with the name "akspl" which, if I am not wrong, is only a sample name in the example(). It goes that way: rast.obj->akspl rast.put(G, akspl, lname="rast.obj", ...) Is that a known problem or have I done something wrong...

Dear users, I got this problem and i don't have a clue of what it could be happening... The context: i'm running a loop in which i extract information from a raster map (I work with GRASS and R, using spgrass6 package), and rearrange it to create a matrix. I've tried it with small maps and it works smoothly, but in large maps I have to resort to saving data in the hard disk regularly in order to avoid the "cannot allocate vector of size..." problem (builted in the loop...
