This question is about workflow and reproducibility. Your project as saved in ETC1010_5510.Rproj is in the folder ETC1010_5510 (which indicates that the location where R is looking at is folder ETC1010_5510). In that folder you have carefully organised your assignment work into a separate directory, which holds your solution, in the file assignment_01.Rmd. The directory structure is below:

users
  └── myself
      └──  ETC1010_5510
            └── ETC1010_5510.Rproj
            └── assignment
                └── assignment_01.Rmd
                └── assignment_02.Rmd
                └── data
                    └── file.csv

What would happen if you tried to run the following code after you opened the project read_csv("assignment/data/file.csv")?

How does semi_join work?

True or False?

The "inner_join()" function will return all rows from x where there are matching values in y and all columns from x and y

What is the difference between the left_join() and the

right_join()?

Select the correct answer

True or False?

“Keys” are variables used to connected records from one table to another.

Animated plots should always be used as it it the best type of graph

Select the INCORRECT statement below.

RProjects:

The facet_grid command allows us to present plots combining two variables

The facet_wrap command allow us to present multiple subplots to display subsets of our data

I will use R projects from now on.
