RStudio is the best IDE so far to use R. Its power is not only coming from the great developers behind it but also it’s an open source product which can be developed and maintained by contributors. I compile a list of some keyboard shortcuts, packages to increase performance and add-ins to boost the productivity that I use in my everyday tasks.
The packages mentioned here just indicates how they can improve the working, not the actual work.
You can measure the performance of computing with microbenchmark which computes each argument 100 times to give results on average. Further, the benchmark can be visualized via
autoplot() function dependent upon ggplot2 package. The alternative of this package in base R is
Profvis is a nice package/tool to understand how R spends its time. I will start trying to use to optimize my Shiny applications.
Lintr package gives you nice ‘linting’ which are gently reminders to have command over your own styling and syntax. Linting suggestions will not not improve performance or speed at all; however, the readability will boost up as the R language should be written for humans at first, and then computers. Therefore, run
RStudio add-ins is just its extension mechanism to customize your working environment. Your productivity can significantly be increased together with lots of useful add-ins which you previously doing by hand spending hard time to fix the things to look it correct. I recently discovered the add-ins and they just great.
Most of the add-ins requires
I here curate the addins I like. You can click here if you prefer to see a more comprehensive list of addins.
More little boxes
Although its name indicates that the boxes are small, for me the comment blocks are too big, which I found myself always scrolling up or down. The add-in is just great, quite helpful to differentiate the code sections visually; however, it needs to be tailored a bit for my needs. The original package is here.
As I use this add-in often, I have assigned a keyboard shortcut for it (Windows/Linux
Ctrl + Alt + H or Mac
Cmd + Option + H). You can customize keyboard shortcuts in RStudio via
Tools > Modify Keyboard Shortcuts....
I have really found datapasta a huge time saver. You can see the GIF above which I recorded in my working environment. It formats, add quotes, and concatenate the lists and vectors. My favorite things it does: 1) Paste (as data.frame and vector) 2) Fiddle Selection 3) Toggle Vector Quotes. It’s dependent upon ‘readr’, ‘clipr’ packages, and uses RStudio’s API (possible to use without it). It’s on CRAN, so installation is easy as
However, I did not find useful yet to assign any keyboard shortcut to any of the provided functions.
A Shiny based GUI theme assistant for
ggplot2 can significantly help your plotting work.
A RMarkdown addin which is useful e.g. when especially constructing tables.
I will list the shortcuts that I usually exercise. For a comprehensive list, you can always visit
Tools > Keyboard Shortcuts Help.

Seeing the customized keyboard shortcuts from the add-ins which are stored in. If you are in any .nix based systems:
cd ~/.R/rstudio/keybindings cat addins.json
If you modified any other shortcuts, also check
Modify RStudio theme with CSS
This part is quite interesting cause it will give you much more control then you need in the console. The technique is originally adapted from this post, which has more detailed explanation. At the same time I update this post, I have R Studio version 1.1.447 (2018-04-18) and R version 3.4.3 (2017-11-30).
Before and after... Nice view!
Steps to do it:
- Choose an area you want to change
- Do a right click and select ‘Inspect Element’
- The console layout like a browser will be opened up
- Scroll down a bit, find and click on the
<link>tag referencing a CSS file
- Play with the CSS selectors in real time
- After you are happy with changes, go to the actual path and overwrite the document
- (do not forget to take a backup of the original file)
- Then your changes are permanent
NOTE: I will keep this post updated as long as new shortcuts, tools and add-ins come along.
