  1. A short introduction to dplyr Juan Natera Los Angeles R

    Meetup 09/04/2014

  2. A bit about me • Software Engineer • Interested in

    R and its use for gaining insights about data • Open Source enthusiast • Baseball fanatic

  3. About dplyr • Developed by Hadley Wickham, Chief Scientist @

    Rstudio. • Part of a suite of packages meant to facilitate working on the “data pipeline”.

  4. Why? • People spend a lot of time getting data

    ready for analysis • Almost no learning curve (just need to learn 5 verbs) • Improves readability • It's FAST

  5. The data pipeline Tidy Transform Model Visualize

  6. The 5 verbs • flter: remove rows • select: choose

    columns • arrange: reorder rows • mutate: change data • summarize: guess...

  7. No learning curve, how? • First parameter is always a

    data.frame • Other parameters describe what you want to do with it. • Always returns a new data.frame

  8. It's Fast

  9. Let's see some code!

  10. A great book I picked up at useR 2014
