Hi Weiwei, (For those stumbling across this thread: the strongly recommended way to install Bioconductor packages is described on the bioconductor web page; generally, do NOT install from a manually downloaded file, unless you want to make life more complicated than it needs to be). To install a package from disk, use install.packages with repos=NULL. See the help pages of install.packages for details, and perhaps the source code for biocLite and biocinstall, both downloaded when you source('http://bioconductor.org/biocLite.R'). 'Automatically unzip' is a configuration issue with the software used to download the file from the internet, e.g., your web browser automatically processing files with a .tgz extension. Configure your software not to do this. I think it's not a good idea to ask what to do with a .tgz file that has been expanded -- you might be able to use 'install.packages' or the command line R CMD INSTALL, or perhaps zip it back up using standard tools ('tar' in your case), and the success of these methods might depend on the content of the package (e.g., compiled C code, versus lazy loaded data, vs, ...) the operating system, etc. In the end you'll spend more time figuring out and confirming that you've done the right thing than you will by downloading the files again. You might investigate download.packages and its 'type' option as a way of creating a snapshot of the appropriate files.
