3.3 Intro to RMarkdown. For example, I can refer to the first section (Section 12) in this document by referring to the section as \@ref(start) because it was written as: # Citing Figures, Tables & Sections {#start} One note here - your slug can not start with a number. After this, it is frustrating, and error prone. To call header hello-world as a header, we type \@ref(hello-world) to cross-reference the section. You can access them in the Word template used. For example: \begin{equation} E=mc^2 (\#eq:emc) \end{equation} It renders the equation below (12.1): E = mc2 (12.1) (12.1) E = m c 2. R Markdown documents are used as the basis for many types of data products. Pandoc: the standalone conversion engine used by the rmarkdown package, comes bundled inside rmarkdown package. To number equations, put them in the equation environments, and assign labels to them using the syntax (\#eq:label). For example: \[\begin{equation} Technically called the yaml header, this section lists the title, author, date and output format. Life expectancy from 1952 - 2007 for Australia.

Once published, an INPUT sidebar will become available in the RStudio Connect dashboard.. Click on the input sidebar to update the parameters and re-run the report. An RMarkdown file is a plain text file that allow us to write code and text together, and when it is “knit”, the code will be evaluated and the text formatted so that it creates a reproducible report or document that is nice to read as a human. In this section we will explore two different ways for referencing text in the document, classical markdown way, supported by rmarkdown::html_document output type and more Rmarkdown specific way supported by bookdown::html_document2 output type. Exploratory Data Analysis. Let's take a quick look at this built in data set. The difference is that when there are not label to link, this way will produce just the plain text [Methods], not a broken link, but otherwise will make the same link that [Methods](#methods). Section 2.5.3 highlighted how equations can be created using LaTeX syntax within Markdown. The layout of the header is very precise and will look like that shown in Figure 1.2, which is currently set to output as HTML. ```{r cool-plot, fig.cap='(ref:cool-plot)'}, boxplot(Sepal.Length ~ Species, data = iris), ```{r cars-plot, fig.cap="A plot caption"}, knitr::kable(mtcars[1:5, 1:5], caption = "A caption"). Otherwise, it will print out the slug. By default, Pandoc will generate IDs for all section headers, e.g., # Hello World will have an ID hello-world.

Figure 1. the keyboard shortcut Ctrl + Alt + I (OS X: Cmd + Option + I); the Add Chunk command in the editor toolbar; or by typing the chunk delimiters ```{r} and ```..
