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 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

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

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 ", ...,

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'm trying to install the packages rgdal and spgrass6 by "install.packages" but i receive always this message: ERROR: configuration failed for package 'rgdal' ** Removing '/home/thyberio/R/i486-pc-linux-gnu-library/2.7/rgdal' ** Restoring previous '/home/thyberio/R/i486-pc-linux-gnu-library/2.7/rgdal' The downloaded packages are in

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 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

Dear all, A very basic terrain calculated as a matrix from Spatial Points Patterns: #interpolate using the akima package library(akima) terrain=interp(ppoints$x,ppoints$y,ppoints$marks,xo=x0,yo=y0, linear=F) > class(terrain) [1] "list" > class(terrain$x) #these are the x-coord i.e: [1...1000] [1] "numeric" > class(terrain$y)#these are the y-coord i.e: [1...1000] [1]

hi, i'm trying to perform a clustering on a big dataframe the code is this: print("load required R packages") require(spgrass6) require(cluster) gmeta6 <- gmeta6() print("read in our 7 raster files from GRASS") x <- readFLOAT6sp(c ("er","crosc","longc","slope","profc","minic","maxic"))

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

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

Wine 1.1.40, Nvidia 7900GS I'm running the game with a static lighting, had to do winetricks d3dx9, since it didn't start without native libraries (xrEngine.exe crashed with an irresponsible bug report window and "wine: Call from 0x7edd1137 to unimplemented function d3dx9_36.dll.D3DXDeclaratorFromFVF, aborting" message in the wine log).

Hello everybody! For my academic project work I intend to use only open-source software. My objective is to carry out classification of satellite digital images using Geostatistics. I found out GRASS is a good software for image processing. Also a good geostatistics software is R. It is also known that R can be used in combination with GRASS. But I am not able to confirm that satellite digital
