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

Let's assume that you have Rtools and devtools on the win machine.

Step 1: Download the source zip.

Step 2: Copy to the win machine and unzip the content there.

Step 3: Run the following code (adjust the path as necessary):

library(devtools)
source <- devtools:::source_pkg("E:/temp/data.table-master")
install(source)

library(data.table)
#loads 1.9.7
