# Integration of R and website

## R Markdown

This is an R Markdown document. Markdown is a simple formatting syntax for authoring HTML, PDF, and MS Word documents. For more details on using R Markdown see http://rmarkdown.rstudio.com.

When you click the **Knit** button a document will be generated that includes both content as well as the output of any embedded R code chunks within the document. You can embed an R code chunk like this:

```
summary(cars)
```

```
## speed dist
## Min. : 4.0 Min. : 2.00
## 1st Qu.:12.0 1st Qu.: 26.00
## Median :15.0 Median : 36.00
## Mean :15.4 Mean : 42.98
## 3rd Qu.:19.0 3rd Qu.: 56.00
## Max. :25.0 Max. :120.00
```

## Including Plots

You can also embed plots, for example:

Note that the `echo = FALSE`

parameter was added to the code chunk to prevent printing of the R code that generated the plot.

## Equation example - not working yet in Rmarkdown… need to check

with backticks
`$S_n = \sum_{i=1}^n X_i$`

without
`\(S_n = \sum_{i=1}^n X_i\)`

with backticks
`$$S_n = \sum_{i=1}^n X_i$$`

without
`$$S_n = \sum_{i=1}^n X_i$$`

Hi `$z = x + y$`

.

`$$a^2 + b^2 = c^2$$`

```
$$\begin{vmatrix}a & b\\
c & d
\end{vmatrix}=ad-bc$$
```
