In jr-packages/efficientTutorial: Efficient R Programming

Learning Unknown Unknowns

My route...

Stackoverflow

Show of hands

Who's "borrowed" code from SO?

Who's asked a question?

Who's anwered a question?

Answering stackoverflow questions

• Regardless of your level, there are questions you can answer

• Even just edit a badly worded question helps

• SO usually takes a few(?) minutes - so closure

What happens if someone gives a better answer?

Who cares!

• Just edit your answer to say XXX is better

Aside

• Never use code you don't understand

• Read about the Nissian dev

Others ways

Use the source!

• Watching the GitHub R source code mirror will allow you to monitor small changes that occur

  • https://github.com/wch/r-source/

• Also, look at how base R functions are written, e.g. NCOL

R-dev Mailing List

• Really useful to see how R is built and the compromises it has to make

• I recommend giving at least a 6 week observing period before asking/answering
