1 Don’t remember everything
You might think there is a lot to remember! No one is able to remember all the functions and which function is from which package. Meanwhile Rstudio cheat sheets are helpful for you to quickly check the functions of many popular packages.
What is important to keep in mind is to design an effective and reproducible data analysis process (just like what the tidyverse flowchart shows), understand what your data and project needs, and then find the right functions!
1.1 Where to get help with R?
When you have trouble using a function or package, you can always seek help from your peers and our CSS slack channel. Rstudio has some suggestions where to get help with R. Most of your questions could have already been answered online. I highlight the following three websites where I normally go for R questions:
Google, of course.
stackoverflow.com It has so much more than R questions.
2 Toy data
R provided a list of built-in data sets, you can use data() to see the full list and load the data set by using data("dataset_name") . (4 points)
