Hello,

I've switched to using a personal library in addition to the main library and noticed an issue using biocLite() to update my packages. When I'm not running as administrator, R can't write to the main library but many of the base R packages get upgraded often. Both upgrade.packages() and biocLite() will ask if I want to install the upgrade in my personal library instead, which is nice, neat and efficient. However, biocLite() when run again will still pick up on the old packages in the main library and think they need to be upgraded, whereas upgrade.packges() is slightly better at apparently noticing the newest packages in my personal library, although it just gives an cryptic warning about "package XXX will not be updated". Is there a way to improve biocLite() so that it compares the package versions in the different library trees and only asks about updating if the one in the library called first is outdated? It's not much of a problem the way it is because it does work, it just does a lot of unnecessary downloading and installing or I have to go through and manually figure out which packages to install.

Thanks, Jenny

  There are binary versions available but the source versions

Do you want to install from sources the package which needs compilation?
