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 . I tried to open it using : grib <- readGDAL("C:\\Users\\aalyaari\\Desktop\\Vol_025_H14_2010060700.grib") but I got this error: C:\Users\aalyaari\Desktop\Vol_025_H14_2010060700.grib has GDAL driver GRIB and has 721 rows and

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.

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
