With blogdown, you are able to take advantage of several features of Pandoc’s Markdown, including adding citations. You can read more about adding citations in the bookdown book here. This post will demonstrate how you can add citations. There are 3 steps: Save a BibTeX file(s) in the /content/post/ directory. The file should be a plain-text file that contains citations that generally look like this: https://www.liechi.org/en/2019/04/r-ntoes/ Tue, 30 Apr 2019 00:00:00 +0000 https://www.liechi.org/en/2019/04/r-ntoes/ This post is an R learning note for myself. It will not be a comprehensive summary on R learning, but highly adapted to my own needs. Learning by using is, I think, the best way to get new skills. I am not sure how widely this idea can be applied, but it works very well for learning programming. I started learning R two years ago, but I still feel I am a stranger to R, and R is a stranger to me. https://www.liechi.org/en/2019/04/statistics-notes/ Tue, 30 Apr 2019 00:00:00 +0000 https://www.liechi.org/en/2019/04/statistics-notes/ This post is for summarizing my statistics learning and using experience. I will update it occasionally. Data description Statistical inference Modelling https://www.liechi.org/en/2017/05/second-test-for-rmd-file/ Thu, 04 May 2017 00:00:00 +0000 https://www.liechi.org/en/2017/05/second-test-for-rmd-file/ If you see this, it means my rmd file is succesfully compiled to a webpage. Now I will draw a plot to display 100 random numbers. x <- 1:100 y <- rnorm(100, 100, 100) plot(x, y) abline(h = 100) In this example, I ran blogdown::build_site() after I wrote the contents, but I received an error like this: Error in loadNamespace(name) : there is no package called ‘xaringan’ Calls: local … tryCatch -> tryCatchList -> tryCatchOne -> Execution halted Error in build_one(unlist(files[i, ])) : Failed to compile content/en/2017-05-04-second-test-for-rmd-file. https://www.liechi.org/en/2017/05/git-in-rstudio/ Wed, 03 May 2017 00:00:00 +0000 https://www.liechi.org/en/2017/05/git-in-rstudio/ If you see this piece on my site, it means I succesfully wrote and pushed a post to my github repository using RStudio only. When I just started blogging with satic site generated by Hugo through blogdown, I was so fresh a freshmen that I had no idea what all these were about. It is a relatively long tool chain from generating the scaffold of my site, hosting the building files on github to publishing it on Netlify. https://www.liechi.org/en/2017/03/the-spirit/ Wed, 15 Mar 2017 00:00:00 +0000 https://www.liechi.org/en/2017/03/the-spirit/ This image is said to be created by John Wheeler. I really enjoy the idea behind this art work, because it reminds me of the idea of Hegel on the cosmos. John’s perception: When you feel the power of thoughts, you feel the power of the cosmos. https://www.liechi.org/en/2017/02/my-first-blog-post/ Sun, 26 Feb 2017 00:00:00 +0000 https://www.liechi.org/en/2017/02/my-first-blog-post/ Hi there.
