d. Create a basic plot of the number of words per book.
e. Create the same plot as (d) but add a title, using an additional argument in your
plot() function. Note that any time you would like to do something extra with a function but don’t know how, you can always use the query command
? before the function name (but without the parentheses) to view a help file, which will explain the various arguments that can be passed to a function. For example,
a. Create a vector of your classmate’s eye colors.
b. Check what kind of vector this is?
c. Create a vector of the number of harry potter books your classmates have read.
d. Plot this vector.
e. Add a title to the above plot.

g. What is the mean shoe size? (Note: you will likely have to use the help file for
x<-1 : 10
mean(x <- 1:10, FALSE)
doSomethingVeryComplicated(data = datafil1,position="here",baseline = na,title="A very long title")
simonSays <- 'It's time's to gets going, y'all!'
You will need to write R code to answer each of the questions.
Please format your answers as follows:
Copy and paste each question, commented out. This ensures that we know which answer corresponds to which question.
Write your R code answer below each question.
It should look something like this:
# LAB: Unit 1. Lab 1 # Your Name # Put your name here # 1. Add 7 and 3,456. 7 + 3456 # 2. Assign this value to an object x <- 7 + 3456
Log into Canvas.
Go to the Assignments page.
Under ‘Labs’, you should find the correct assignment.
Copy and paste your R code into the text box.
Click ‘Submit Assignment’.
You are permitted to submit your answers as many times as you like within each Unit.
Answers will be graded two or three times a week and re-opened if you submit early.
Each lab will close at its respective deadline (see Canvas).
Final grades for each lab will be computed and entered into the Canvas gradebook at the end of each Unit.
