installing odfWeave to R in an offline environment

as title, I want to try odfWeave, but the network in my office is so restricted that I can't access the repos outside, is there anything I can do to install the odfWeave package?

Thanks!

P.S. I am using R-portable 2.11.0, I have tried Rtools but it prompt me with an error of package XML not found, which is not true

If you're absolutely sure that you have the correct package XML installed, and you're absolutely sure it's installed correctly, then you can just download the source of the odfWeave package and install from there. You don't need Rtools for that, just do :

install.packages(
    c("path/to/file/odfWeave_x.x.xx.tar.gz",
    repos = NULL,
    type="source"
)

If / when it becomes available, you could install from the downloaded binary for windows, but then you have to set type to "win.binary" or "win64.binary" depending on the version you have.
