Jun Duan http://yihui.name 2016-11-10T22:23:38+00:00 jonduan@uvic.ca Julia Tutorial http://jonduan.github.io/en/2014/08/Julia/ 2014-08-02T00:00:00+00:00 Jun Duan http://jonduan.github.io/en/2014/08/Julia I am R user. I am pretty fond of the beauty of R.

I am also a Matlab and Python user.

Then I find Julia has features of R, Python, and Matlab.

  1. scipy_2014_julia

  1. MIT has a tutorial about Julia as well.

I hope I can use Julia can meet most of my need for scientific computing.

I am supprised that there are Julia Studio like Rstudio and IJulia Notebook like IPython Notebook.

  1. Julia Studio is still very simple and is not nice as Rstudio.

  2. But IJulia Notebook is pretty. It is based on IPython Notebook. IJulia is a Julia-language backend combined with the IPython interactive environment.

I find software carpentry gives a lot of good advices. I even find many statisticians support this project. Thousands thanks for those great people.There is good video about it https://www.youtube.com/watch?v=1e26rp6qPbA

]]> IPython vs knitr, or Python vs R http://jonduan.github.io/en/2014/07/ipython-vs-knitr/ 2014-07-23T00:00:00+00:00 Jun Duan http://jonduan.github.io/en/2014/07/ipython-vs-knitr ipython and knitr

I am econometrics student. I first learned R and knitr, and then I learned a little Python and IPython notebook. They are similar. I am wondering why smart people usually have the same idea.

I just find that I can use R and Octave in IPython notebook.

There is youtube video show how we can do it.

If R is not flexilbe as Python does, I may transfer to Python.

]]> Markdown or LaTeX? http://jonduan.github.io/en/2013/10/markdown-or-latex/ 2013-10-19T00:00:00+00:00 Jun Duan http://jonduan.github.io/en/2013/10/markdown-or-latex This is my favorite post on yihui's blog. Markdown or LaTeX?

I start to use markdown in stead of latex for the same reasons.

]]> Use LyX/knitr to write a R journal http://jonduan.github.io/en/2013/02/write-the-r-journal-with-lyx-knitr/ 2013-02-17T00:00:00+00:00 Jun Duan http://jonduan.github.io/en/2013/02/write-the-r-journal-with-lyx-knitr I am going to follow this post's suggestion to use Lyx/knitr. Contribute to The R Journal with LyX/knitr

]]> Lyx or Emacs http://jonduan.github.io/en/2012/10/lyx-vs-latex/ 2012-10-30T00:00:00+00:00 Jun Duan http://jonduan.github.io/en/2012/10/lyx-vs-latex I use Lyx for Latex the same as many people in our department. I mainly use sublime for markdown and text files.

There is interesting slide about "Emacs Has No Learning Curve" or https://stat.ethz.ch/pipermail/ess-help/2012-August/008067.html

Now I rather use Rstudio and knitr.

]]> How to Make HTML5 Slides with knitr and slidify or shiny http://jonduan.github.io/en/2012/05/how-to-make-html5-slides-with-knitr/ 2012-05-01T00:00:00+00:00 Jun Duan http://jonduan.github.io/en/2012/05/how-to-make-html5-slides-with-knitr I use beamer once. And then I know there are knitr, slidify, and shiny in the R environment. They are much more beautiful. http://shiny.rstudio.com/ I have done some works by using them. Much easier, more flexible.

]]> Reproducible Research http://jonduan.github.io/en/2012/03/reproducible-research/ 2012-03-15T00:00:00+00:00 Jun Duan http://jonduan.github.io/en/2012/03/reproducible-research Everything I learned about reproducible research is related to this post.

Ideas on A Really Fast Statistics Journal

Jeff and Roger are the best teachers in terms of R.

]]> Why I need github? http://jonduan.github.io/en/2011/12/why-github/ 2011-12-12T00:00:00+00:00 Jun Duan http://jonduan.github.io/en/2011/12/why- github I started to use github since I took Roger's coursera courses. And now I found I cannot do my work without it.

This yihui's post says many things I want to say. How to Become an Efficient and Collaborative R Programmer

]]> Customizing the Theme of Your R HTML Help http://jonduan.github.io/en/2011/01/customizing-the-theme-of-your-r-html-help/ 2011-01-04T00:00:00+00:00 Jun Duan http://jonduan.github.io/en/2011/01/customizing-the-theme-of-your-r-html-help I will say following Yihui's suggestion:

R's default theme of the HTML help pages is too plain for me to read, but we can easily modify the theme, which is essentially a CSS file. You can find the file under:


file.path(R.home('doc'), 'html', 'R.css')

Simply replace this file with my version of [R.css](https://github.com/yihui/configuration/raw/master/R.css) (1K) which looks like:

R HTML Help Theme

Of course you can design your own `R.css` if you know CSS.
