TeXnicle is my favourite editor for writing LaTeX documents. It is available for Max OS X. So I’d like to use it when writing knitr‘s Rnw-files. Rnw-files are LaTeX-files with embedded R-code in it. So Rnw-files need to be preprocessed. The result is a tex-file which will be compiled by pdflatex or xelatex. Processing is done by so called engines. TeXnicle comes with a bunch of different engines. You can see them in preferences (hit ⌘-,) on tab “Typesetting”.

Sometimes you want to use some custom fonts in your ggplot2 graphics. Years ago there was a good article in [revolutionanalytics.com]. But this article states that if you want to use otf-fonts instead of ttf-fonts you have to use some experimental packages: 1 2 3 library(devtools) install_github('wch/Rttf2pt1') install_github('wch/extrafont') But as time goes by the evolution of R-packages progresses. So now you can use otf-fonts in ggplot2 graphics. I’m using Source Code Pro as custom font because I can identify this font really good because of its “zeros”.

I really like to work with R. So I want to share here some of my experience, tips and tricks I use in my daily work. Most of the time I use the following R-packages: ggplot2 dplyr RGoogleAnalytics knitr
