Superscript Test

\(R^{2}\)

R^{2}

[

f(x) = \frac{1}{(\sigma\sqrt{2 \pi})} e^{-(\frac{(x - \mu)^2}{2 \sigma^2})}

R Normal Distribution Functions

Density, distribution function, quantile function and random

generation for the normal distribution with mean equal to ‘mean’

and standard deviation equal to ‘sd’.

Use them this way:

```
dnorm(x, mean = 0, sd = 1, log = FALSE)
pnorm(q, mean = 0, sd = 1, lower.tail = TRUE, log.p = FALSE)
qnorm(p, mean = 0, sd = 1, lower.tail = TRUE, log.p = FALSE)
rnorm(n, mean = 0, sd = 1)
```

The math behind the code:

\[

f(x) = \frac{1}{(\sigma\sqrt{2 \pi})} e^{-(\frac{(x - \mu)^2}{2 \sigma^2})}

\]

Ten random draws from the normal distribution:

```
library(ggplot2)
qplot(1:10, rnorm(10), colour = runif(10))
```

Test of markdownToHTML Output

\[f(x) = \frac{1}{(\sigma\sqrt{2 \pi})} e^{-(\frac{(x - \mu)^2}{2 \sigma^2})} \]

This is an R \(\sigma\) Markdown document. Markdown is a simple formatting syntax for authoring web pages (click the **MD** toolbar button for help on Markdown).

Another inline \( \sigma\sqrt{2 \pi} \) math equation.

here’s markdown superscript in action e^{2} and math inline equivalent \(e^2\).

This is an R \(\sigma\) Markdown document. Markdown is a simple formatting syntax for authoring web pages (click the **MD** toolbar button for help on Markdown).

When you click the **Knit HTML** button a web page 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
## 1st Qu.:12.0 1st Qu.: 26
## Median :15.0 Median : 36
## Mean :15.4 Mean : 43
## 3rd Qu.:19.0 3rd Qu.: 56
## Max. :25.0 Max. :120
```

You can also embed plots, for example:

```
plot(cars)
```
