Have three options: + Listen and take notes as I go through the handout + Print out PDF and take notes as I go through the handout (posted to Slack #in-class) + Run the code with me (grab handout from `/home/courses/math141f20/Handouts`) --- ## Week 3 Topics * Data summarization * **Data wrangling** * Data collection --- # Goals for Today * Review the main `dplyr` verbs -- * Practice wrangling -- * See more wrangling examples --- ## Sage Advice from ModernDive > "Crucial: Unless you are very confident in what you are doing, it is worthwhile not starting to code right away. Rather, first sketch out on paper all the necessary data wrangling steps not using exact code, but rather high-level pseudocode that is informal yet detailed enough to articulate what you are doing. This way you won’t confuse what you are trying to do (the algorithm) with how you are going to do it (writing dplyr code)." --- class: center, middle, inverse # Let's practice wrangling!
