a) There are various routes to modifying sources.list... Ubuntu Software Center has a dialog box for it, and there are several other such tools.
b) I always copy-pasted from the instructions so I had no problems with fiddly bits.
c) Not all mirrors are created equal... sometimes you need to pick a different one to get the right combination of updated software and libraries. This changes over time, so I have never had the perfect storm of repository problems and new installation unfamiliarity to deal with.

I got R to update to the latest version The problem was the sources.list file. I had not fixed the sources.list file correctly, which was apparent when I opened the file using sudo nano sources.list Opening the file from the command line turns on syntax highlighting (as opposed to opening a file from within nano using ctrl-r... who thinks of these shortcuts? Ctrl-o means "save"?) anyway... it's very important to have a space and a trailing slash... as shown below: deb http://ftp.ussg.iu.edu/CRAN/bin/linux/ubuntu precise/ When I edited that line, the update worked. Hope this helps someone. Thank you, Gene Leynes

Can I install version 15.1? I changed my sources.list to be a current cran mirror. I believe that I have entered the URL correctly because at first I had it wrong (there was a trailing "/"), and I fixed that error. when I run sudo apt-get install r-base it says that I'm at the most current version, but I can see 15.1 in the repository. > sessionInfo()R version 2.14.1 (2011-12-22) Platform: x86_64-pc-linux-gnu (64-bit) locale: [1] LC_CTYPE=en_US.UTF-8 LC_NUMERIC=C LC_TIME=C LC_COLLATE=C [5] LC_MONETARY=C LC_MESSAGES=C LC_PAPER=C LC_NAME=C [9] LC_ADDRESS=C LC_TELEPHONE=C LC_MEASUREMENT=C LC_IDENTIFICATION=C attached base packages: [1] stats graphics grDevices utils datasets methods base loaded via a namespace (and not attached): [1] tools_2.14.1 > Thank you, Gene Leynes _____________________________________________ *Data Scientist* *http://www.linkedin.com/in/geneleynes * <http://goog_598053156>*http://geneorama.com/ <http://geneorama.com/%20>*
