similar to: readVECT6 and readRAST6 fails with R and GRASS 7 ???

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 (There were some threads from 2009 where spgrass6 wasn't working with GRASS7 yet, but I assumed that information was out of date.) So I figured I was doing something wrong with the library and package

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 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:

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

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 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: #

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

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

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 trying to install the rgdal package on my Mac OS X 3.9. I downloaded and installed the GDAL libraries from Fink and then tried to install rgdal and got the following message. I tried to determine if the GDAL libraries were in my path but I'm not sure how to do that. Any ideas? Thanks. trying URL 'http://www.biometrics.mtu.edu/CRAN/src/contrib/rgdal_0.4-10.tar.gz'

Hi All, Not a new R user, but new to R with Linux, specifically Ubuntu Hardy Heron 8.04 64bit. I have had success installing common packages using the typical R interface (in Linux), but have had problems installing less common packages like (rgdal) and (RSAGA) that are not loaded with R. I'm wondering if there are any tricks to these libraries that won't install, from reading the

Hello, I run [R] 2.14 on Mac OS 10.6 and I've been desperately trying to install rpy2 in order to compute spatial statistics on QGIS 1.7.3. rpy2 is dependent upon the rgdal [R]package that I've been unable to install in spite of up to date versions of GDAL and PROJ. More precisely, [R] console writes "Error: gdal-config not found". As a matter of fact, typing
