Installing a package offline from GitHub

Question

I\'m trying to port some packages to an R installation on an offline (Windows) computer.

From CRAN (let\'s say data.table), the process: 1) download .zip

Answer 1

Not sure if this is a solution or a workaround. Given a zip file of the source of an R package directory structure:

On a shell:

~$ unzip data.table-master.zip
## optional renaming
~$ mv data.table-master data.table
## create the new
~$ tar czf data.table.tar.gz data.table

There are likely other tools that allow you to extract and re-archive them in a different format. Since I tend towards shell-level access and control, I tend towards these simple tools.

In R:

install.packages("data.table.tar.gz", type="source", repos=NULL)

(This will not succeed unless all dependencies are already installed.)
