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 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

Dear all, I have some additionale question concerning the spgrass6 package. * When you set a region in GRASS, does the readGRASS6 function in R only load data contained in the zoomed region or the whole map ? * When you have a MASK map in grass, does the readGRASS6 function in R only load data contained inside the MASK area ? Could this be the problem ? Thanks, Jessica

Hi I am working with spgrass6 package and GRASS v.6.2. Everything was fine until I tryed to read a vector file with readVECT6 (and other related vector commands, like vInfo). When I ran these commands, the problem immediately appeared (" Sorry, is not a valid flag" ). Ok, the solution is easy: - You have to download the spgrass package within a folder, in order to install

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't get how to handle

Hello everybody, I am a new R & Grass user. I am interested in doing a kriging of the Temperature in a basin, based on pixel elevation (DTM). I use Grass 6.2.1 and R 2.5.1 and have installed the spgrass6 package. The DTM is called "DTM_trentino_100m" and is like this: north:5158000.0 south:5058500.0 east:1729700.0 west:1611600.0 rows:995 cols:1181 -9999.0 -9999.0 -9999.0

Hi if I try to import a raster layer which consists only of NULL values from grass by using the readRAST6, I get an error message: > readRAST6("HSericea_seedsDisperse_2007") ERROR: Invalid value for null (integers only) Error in readBinGrid(rtmpfl11, colname = vname[i], proj4string = p4, integer = to_int) : no such file:

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: #

Hello everyone! I am using GRASS with spgrass6 for my work. I will be using variograms in the process of landsat image classification. I am quite ok with GRASS but am finding R really tough. I understand that spgrass6 is a link between GRASS and R which can read and write raster/vector layers. Out of really many packages in R, for generating variograms out of landsat images which packages of R

Hi, I tried to install R packages required for the GRASS-R interface by using the following command (copied from http://www.geog.uni-hannover.de/grass/statsgrass/grass6_r_install.html): /install.packages (c("sp", "spgrass6","rgdal","maptools"), dependencies =TRUE)/ rgdal package was installed successfully; There were problems to find 'sp' and

Thank you for providing the example code... for the request of running it multiple times it would have helped if you could have confirmed that the example ran through without errors... there were a lot of mistakes in it. Look into using the reprex package to check your example next time. I don't do this kind of analysis... I really don't know what to expect from the functions. The

I am using GRASS 5.7 and R 2.0 for OS X. I have a simple xy location I am doing some theoretical work with and would like to import maps into R using the interface in order to do analyses. Yet when I attempt to do this, I get the following error: >G<-gmeta() Error in gmeta() : region for current mapset is invalid line 11: <top: 100> run "g.region" I traced the

Hi, I am still a bit of a beginner with R but I had it all working spgrass6, RMySQL, sp, etc... Then I wanted to install spatstat, this required updating R, all was going fine until I tried to connect to grass gis using spgrass6 library, it wouldn't let be install the package due to a dependency with rgdal. rgdal will not install as the sp package is 1:0.9-56-2 and sp requires a higher

Greetings: As I am not a windows user, I cannot try this: is it possible to install rgdal on windows without having to compile it from source ? Compilation on MacOS is within my abilities, however each time i try and install the rgdal package it dies complaining that it cannot find gdal-config --- which was recently installed with GRASS. I have updated my PATH environment variable, logged
