Pascal Thank you for your reply. I have installed GDAL 1.9 Complete [33.6 MiB] (Snow Leopard & Lion) 2012-6-21. I have also had no problem installing the the rgdal library for R 2.15 direct form the rgdal_0.7-11.tgz. Finally, I have updated and sourced my .bash_profile file to ensure GDAL, PROJ, GEOS, SQLite3 and UnixasimageIO can all be found, as follows:
export PATH=/Library/Frameworks/GDAL.framework/Programs:$PATH export PATH=/Library/Frameworks/PROJ.framework/Programs:$PATH export PATH=/Library/Frameworks/SQLite3.framework/Programs:$PATH export PATH=/Library/Frameworks/UnixImageIO.framework/Programs:$PATH export PATH=/Library/Frameworks/GEOS.framework/Programs:$PATH Lastly, I have foolowed instructions on CRAN and entered > setRepositories(ind=1:2) I then used your command and got the following: Installing package(s) into ‘/Library/Frameworks/R.framework/Versions/2.15/Resources/library’ (as ‘lib’ is unspecified) Warning in install.packages : cannot open: HTTP status was '404 Not Found' Warning in install.packages : cannot open: HTTP status was '404 Not Found' Warning in install.packages : unable to access index for repository http://cran.cnr.Berkeley.edu/bin/macosx/leopard/contrib/2.15 Warning in install.packages : package ‘rgdal’ is not available (for R version 2.15.0) I saw this problem earlier today. That is why I pulled rgdal_0.7-11.tgz direct from http://www.kyngchaos.com/macosx/index, which has the latest files for GDAL, PROJ4 and the rgdal package. -- View this message in context: http://r.789695.n4.nabble.com/rgdal-package-load-problem-tp4634134p4634157.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
