This is a quick list of tips/commands I have found useful when tidying up the resulting Rmd files when converted from the LaTeX source.

### Sections

A chapter or section is simply marked with hashtags and automatically given a reference label for example `# First Chapter `

would give a section named ‘First Chapter’ with the ID label `first-chapter`

.

You can give your own ID label to a section or chapter by using `# First Chapter {#bananaboots}`

where the label you give it can be anything you like.

Any subsections are simply denoted `## First Subsection`

and `### First subsubsection`

and so on (they can also be labelled in the same way).

### Equations

LaTeX commands can be used for equations including the $ notation. To label an equation you can use:

```
\begin{equation}
e^i\pi + 1 = 0
(\#eq:euler)
\end{equation}
```

An equation array is also easy to include and label:

```
\begin{equation}
\begin{aligned}
\sin^2(\theta) + \cos^2(\theta) &= 1\\
\sec^2(\theta) - \tan^2(\theta) &= 1
\end{aligned}
(\#eq:array)
\end{equation}
```

### Figures

The figures convert well, generally, as long as the file paths are correct. You will get the Markdown command that lloks something like this:

`![Figure caption](figure.png){width=100%}`

But if you want a little more control and to include a label, you can use something like this:

````{r echo=FALSE, label, outwidth='70%', fig.show='hold', fig.cap='This is the caption'}``knitr::includegraphics("figure.png")`

```

### Tables

Again these tend to convert well, but again if you want to start from scratch or include a bit more control and labels, I found this works:

```
Table: (\#tab:tablelabel) The interesting caption.
|Column 1|Column 2|Column 3|
|:-----|:-----|-----:|
|Row 1|a|b|
|Row 2|c|d|
```

The |:—| sets the alignment for the column.

### Cross-referencing

After labelling your sections they can be referred to using `\@ref(bananaboots)`

.

Equations can be referenced using `\@ref(eq:euler)`

, figures `\@ref{fig:label}`

and tables `\@ref{tab:tablelabel}`

.

### Miscellaneous formatting I found useful

#### Centre test, figure, table etc:

```
::: center
![caption](figure.png){width=50%}
:::
```

#### Display:

```
::: tmframed
This sentence is displayed.
:::
```

#### Bold text:

`___Something bold___`

#### Italic text:

`* This is rendered in italics *`

#### Display in a box:

```
:::: {.textbox data-latex=""}
$$e^i\pi + 1 = 0$$
:::
```

The properties of the box can be specified in the style.css file for the project.
