eh, my old website has been dead since >2 years. I have now finaaaaaaaaaaaly migrated to blogdown, a great r package developed by Yihui, based on Hugo. This site is currently deployed on Netlify - blogdown simply makes a website a folder of static files, and can be put on any web server.
as from a while ago, rstudio interface enables the Terminal (Shell) tab, right next to the Console, I can simply update my changes in the Terminal tab by runing following three lines, isn’t it a joy!
git add .
git commit -m "updates"
git push -u origin master
