I can't download "BSgenome.Hsapiens.UCSC.hg19_1.4.0" through R due to limitations in my network. I have manually downloaded the file. Where should I put the downloaded file? I mean where R stores downloaded bioconductor packages befor installation? I want to execute "biocLite" after that and the script only decompress and install it. I mean I don't want it to start downloading again.
