To compare for example a package's current master on github with a given commit ID, this script helps you install that commit ID of the package with a new package name <package>.<commit_id> (default), or any name you like (via --alias option).
Here I show how to download and use the script to install commit 8c7c61b for susieR package as susieR.8c7c61b, so one can test / compare susieR.8c7c61b::susie() vs susieR::susie(). To run the script you need to have sos command available (via pip install sos).
Download:
wget https://raw.githubusercontent.com/gaow/misc/master/workflow/commmit_install/commit_install.sos \
&& chmod +x commit_install.sos
Install the aforementioned commit:
./commit_install.sos --pkg stephenslab/susieR --commit 8c7c61b
You should see on screen:
other attached packages:
[1] susieR.8c7c61b_0.8.1.0545
To remove this package after use,
R --slave -e "remove.packages('susieR.8c7c61b')"
