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?

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

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

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

The facet_grid command allows us to present plots combining two variables

Select the INCORRECT statement below.

RProjects:

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

I will use R projects from now on.
