Turn messy R scripts intocleaninteractivereproducibleonlinereports
An interactive mini course helping R developers be So. Much. More. efficient at data analysis.
The struggle is real
For the 10th time you open your script called my_analysis_final2.R
.
You're ready for a last run, creating a few graphs that you will have to copy paste to your report, together with some crucial statistical test results.
๐ฑ Bummer!
Did you really write this? It is barely readable. There are no comments. Some lines are so long you can't see their ends. It basically looks like a labyrinth of duplication, making even the smallest changes an agonizing ordeal.
But wait ๐ค. Where is the awesome piece of code you wrote the other day? Perhaps in another version of the script...
Nevermind, let's email those results to the team, it is not too bad already. At least you did not lose your script like last time.
Wait.. No!
You run the analysis on data_clean.csv
instead of data_final.csv
. Results are all wrong! ๐
There is an easier way!
I remember those good old days so well.
But some tools can make your life 100x easier ๐
