What is LaTeX?
•
A text editor for more advanced documents, especially those including
complex tables and equations
•
Uses “code” to create a PDF
•
Useful for projects, homework, manuscripts, quals, posters, figures
•
Examples (These are local to my computer and won’t open if you
click them.)
•
Conference Slides
•
760 homework

{Homework Examples}

Equation Environments
•
$’s allow you to enter in and out of equation mode.
Exercise 1: In words, describe what m and b are in the equation
y = mx + b.
$m$ is the slope and $b$ is the intercept.
Nguyen (UNC) LaTeX Workshop 10/13/2017 6 / 31
Equation Environments
•
$’s allow you to enter in and out of equation mode.
•
Double $ centers the equation.
Exercise 2: Write y = mx + b as a centered equation.
$$y = mx + b$$
Nguyen (UNC) LaTeX Workshop 10/13/2017 7 / 31
Equation Environments
•
$’s allow you to enter in and out of equation mode.
•
Double $ centers the equation.
•
The equation environment will also give you centered equations.
Exercise 3: Write y = mx + b as a centered equation in the equation
environment.
\begin{equation} y = mx + b \end{equation}
Nguyen (UNC) LaTeX Workshop 10/13/2017 8 / 31
Equation Environments
Alignment in LaTeX:
•
Align columns with & symbols
•
Align rows with \\
Notice the nested enumerate environments so that we have problems 3a
and 3b.
Nguyen (UNC) LaTeX Workshop 10/13/2017 9 / 31
Equation Environments
Exercise 3a: Rewrite the equation using the equation and aligned
environments.
\begin{equation}
\begin{aligned}
& & y & = mx + b \\
& & & = (m \times x) + b \\
& \implies & 0 & = \{(m \times x) + b\} - y
\end{aligned}
\end{equation}
Nguyen (UNC) LaTeX Workshop 10/13/2017 10 / 31
Equation Environments
Exercise 3b: Split the last line of 3a onto two different lines
0 = {(m × x)
+ b} − y
\begin{equation}
\begin{aligned}
0 &= \{(m \times x) \\
&\hspace{1cm} + b \} - y \nonumber
\end{aligned}
\begin{equation}
Nguyen (UNC) LaTeX Workshop 10/13/2017 11 / 31
Piecewise functions
Exercise 4: Use alignment syntax and the cases environment to make the
following piecewise function
y =
(
x, 0 < x < 1
mx + b, x ≥ 1
$$ y = \begin{cases}
x, & 0 < x < 1
mx + b, & x \geq 1
\end{cases} $$
Nguyen (UNC) LaTeX Workshop 10/13/2017 12 / 31
Matrices and vectors
What if we have matrices and vectors? Exercise 5: Replicate the following.
E[Y |X] = β
1 0 0
0
.
.
.
0
0 0 1
+
$$ E[\bs{Y}|\bs{X}] = \bs\beta \begin{bmatrix}
1 & 0 & 0 \\
0 & \ddots & 0 \\
0 & 0 & 1
\end{bmatrix}
+ \bs{\epsilon} $$

More Math Practice
Exercise 6: Replicate the following.
s =
P
n
i=1
(y
i
− y)
2
n − 1
1/2
$$ s = \l( \frac{ \sum {i=1}^n (y i - \overbar{y})^2 }{n - 1} \r)^{1/2} $$
Nguyen (UNC) LaTeX Workshop 10/13/2017 14 / 31
Lists
•
Use itemize instead of enumerate to make a bulleted list
•
Sometimes we want to skip numbers or letters in enumerate
•
Note the commands \addtocounter{enumi}{3} and
\addtocounter{enumii}{2} in our next section
•
The number of i’s in “enumi” the first set of brackets determine what
level of the enumerate to add a counter to
•
The number in the second set of brackets determines how many to
add to the counter (Does not set the counter to that value)
Nguyen (UNC) LaTeX Workshop 10/13/2017 15 / 31
Floats
•
Tables, figures, and equation environments are what are called floats
•
LaTeX will try to put these wherever it thinks is best
•
It is generally best to add these to your document last and then play
around with how to position it properly
Nguyen (UNC) LaTeX Workshop 10/13/2017 16 / 31
Figures
Typically, you would do the following, but because we uploaded the entire
.zip, we can skip steps 1-2 for now.
1 Select PROJECT > Files... > Computer
2 Drag and drop or select the image file from your downloaded folder.
3 Use the following code to include the image in your document.
Exercise 4c:
\begin{figure}[h!]
\centering
\includegraphics[scale = 0.3]{Histogram.png}
\label{fig:malezinc} \caption{A histogram of serum
zinc levels in men.}
\end{figure}
Nguyen (UNC) LaTeX Workshop 10/13/2017 17 / 31
Figures
•
The [h!] forces the location as best as possible, based on the size of
the image. Some options are t for top, b for bottom, h for here
(inline).
•
You can play with the [scale = ] option to resize. Instead, you
could use [height = <value>, width = <value>,
keepaspectratio]
•
You can also include a command in the figure environment,
\label{<name>}. Then in your article text, you can use Figure
\ref{<name>} to correctly call the figure number, e.g., “Figure 1”
Nguyen (UNC) LaTeX Workshop 10/13/2017 18 / 31
Tables
\begin{table}[h!]
\caption{Parameter estimates for Model 1.}
\centering
\begin{tabular}{ccc}
\hline
Effect & Variable & Estimate \\
\hline
Intercept & $\beta_0$ & 0.45 \\
Gender & $\beta_1$ & 4.74 \\
Age & $\beta_2$ & 7.32 \\
\hline
\end{tabular}
\label{tab:Model1}
\end{table}
Now, try changing one of the c’s after tabular to an l or r. Then try
adding a | between them. Note the changes in your table.

Including Code
•
We sometimes wish to include our code as an appendix or in a
problem
•
We can use the lstlisting environment for R or the minted
environment for SAS
•
Whatever is typed in this environment is produced exactly as is in the
document in a different font
Nguyen (UNC) LaTeX Workshop 10/13/2017 20 / 31
Including Code
•
R in text
\begin{lstlisting}[language = R, caption = R Code]
x <- rnorm(100)
\end{lstlisting}
•
R file
\lstinputlisting{<filename>.R}
•
SAS in text
\begin{lstlisting}[language = SAS, caption = SAS Code]
PROC FREQ ...
\end{lstlisting}

My Project is Finished. Now What?
•
To download a copy of the pdf, simply click PDF
•
To download a copy of the pdf, tex file, and all accompanying files,
select PROJECT > DOWNLOAD AS ZIP
•
Works similarly to Google Docs
You can also create templates and quickly make copies on Overleaf

Tips and Tricks
•
Use \text{} to include text in equation environments.
•
\textbf{text} will produce boldface font
•
\emph{text} will produce italicized font
•
\hat{} and \tilde{} work similarly to \overbar{}
•
Use the tilde apostrophe to make “quotes” face the correct way.

Tips and Tricks
•
We can make different colored text with \{red}{text}
•
If you are including a float in your homework for a part of a question
(say problem 10c, for example), LaTeX may not place the float where
you like it with respect to the problem numbering. If you add text
before your table or figure environment, this should make it more
aesthetically pleasing.
•
Rmarkdown package in R allows you to write up your LaTeX file in R
so you can more directly import tables and figures as you edit them.
•
You can also create presentations in LaTeX (called beamer). A
template is available on the BSA website
•
Cheatsheet and symbols .pdfs are useful resources.
