Thanks for Yihui Xie and his GitHub repo, I find a good way to write blog in Rmarkdwon, which could support dynamic documentation, and display code and result simutaniously, and the command is pretty simple in RStudio.
servr::jekyll()
Now, this blog is hosted by GitHub, which provide a free jekyll server for bloger.
My main editor switch from Atom to RStudio, which give me a more powerful computation and interactive environment.
