I have this https://echange-fichiers.inra.fr/get?k=6TdTdezNeZwAqJtpwVm grib file which is a regular lat-lon 0.25x0.25 degrees and contains 4 fields .

Hello all, I recently installed rgdal 0.5.24-1 (kyngchaos framework) and I am having trouble making sense of the row, col information provided. > a = new("GDALDataset", "dummy.tif") > GDALinfo("dummy.tif") rows 420 columns 660 bands 1 ll.x -55.5 ll.y -14.5 res.x 0.008333334 res.y 0.008333334 oblique.x 0 oblique.y

Folks: I am getting a build failure when I: #' @importFrom utils shortPathName which roxygenizes it to the NAMESPACE. I suspect this is because this particular function is Windows-only, but I'm a bit confused how I should "properly" importFrom a function like this so it doesn't cause a build failure, but I don't get a note in my R CMD CHECK if I DON'T have it:

1. You should always cc the list unless there is a clear reason not to. 2. You still have failed to follow the posting guide: You say you have difficulty troubleshooting your code, but you have shown us no code. You got an error message that seems explicit, but with neither code nor data, I do not know whether anyone can make sense of it. In any case, I certainly cannot. Cheers, Bert Bert

Hello! I've got troubles on following thing: As output I need a string like: INPUT_FILENAMES = H:\\AKK_temp\\Modis\\MOD13Q1\\austria\\MOD09Q1.A2008073.h18v04.005.2008083134952.hdf|H:\\AKK_temp\\Modis\\MOD13Q1\\austria\\MOD09Q1.A2008073.h19v04.005.2008082182221.hdf The filenames (dates) are with pathname (wrkdr) and separated with "|". The number of input filenames changes

I am using the R-package MODISTools (different than MODIS) and am having a lot of difficulty troubleshooting my code. I have spent awhile going through MODISTools tutorials, searching for my error code, looking at the source code. However, I have not been able to find any relevant information related to my error message. The study I am currently working on involves a herd of 200 African buffalo

R-geographers... I'm trying to solve a problem to implement a line-by-line tiled processing using RGDAL (read 1 line of an image, process the one line, write one line of the image to a binary file). Everything except for the final step I'm able to do using a combination of RGDAL and r-base commands. Below is the basic structure, the input file "elev" can be any image file

Hello, I was wondering if there has been any progress in developing a package for accessing opendap/dods data using R. I see from the list archive that there was some initial work done on this.

I am using MODIS Tools and am having a lot of difficulty troubleshooting my code. I am a PhD student studying African buffalo in Kruger National Park, South Africa. The study I am currently working on involves a herd of 200 African buffalo caught every six months for 4 years. I am trying to use EVI and NDVI to assess seasonal variation thus I would like mean EVI and NDVI for each observation

Dear all, I have a so large image (43,000 x 18,000 pixels) and I need clip this image with a smallest one (1000x1000 pixels). I can read the second image using rgdal package. But the first image can´t be read on my system because if memory limitation (I have about 2GB availabe). So I would like hear from you if anyone have some suggestin in this regards. I have also ArcGis 8.6 ans Erdas 8.3

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'

I am not new to R, but I am new to .grib files. I am downloading some climate data and I would like to analyze it in R. R has a nice netcdf package, but I don?t see any package available to deal specifically with grib files. I see a few posts from other people using grib files in R. However, I was unclear if they used grib files in a different software program and then imported the data
