Text

Some commonly used formatting written in markdown is shown below, which you may recognize from the Git tutorial:

# This is a heading

This is a paragraph.
This line-break will not appear in the output file.\
But this will (since the previous line ends with a backslash).

This is a new paragraph.

## This is a sub-heading

This is **bold text**, this is *italic text*, this is `monospaced text`,
and this is [a link](http://rmarkdown.rstudio.com/lesson-1.html).

An important feature of R Markdown is that you are allowed to use R code
inline to generate text by enclosing it with `r `. As an example: 112/67 is
equal to `r round(112/67, 2)`. You can also use multiple commands like this:
I like `r fruits <- c("apples","bananas"); paste(fruits, collapse = " and ")`!

The above markdown would generate something like this:

Instead of reiterating information here, take a look on the first page (only the first page!) of this reference. This will show you how to write more stuff in markdown and how it will be displayed once the markdown document is converted to an output file (e.g. HTML or PDF). An even more complete guide is available here.

• Try out some of the markdown described above (and in the links) in your template R Markdown document! Press Knit to see the effect of your changes. Don't worry about the code chunks just yet, we'll come to that in a second.
