I am using ubuntu 14.04. I want to set up myself just one library path for R where all of the packages would be installed. I tried setting up environment variables R_LIBS, R_LIBS_USER in .bash_profile (of course running source ~/.bash_profile afterwards), tried adding .libPaths(.libPaths()[1]) to Rprofile.site, but the only thing that I achieve is that my own library is added to 3 other already present ones. Due to this I am getting errors when some packages are from other R version that was previously installed. I want to leave just one library path and prevent R from searching in all others. I found several threads about the issue but neither of them worked for me:
Remove a library from .libPaths() permanently without Rprofile.site

I can try just uninstalling all of the packages and reinstalling them over, but I kind of want everything to be structured and organized anyway. I do not like very much that R shuffles libraries into different folders and want to have just one or max two that were defined solely by me.
