*This post is just a shoutout to the R world and to test whether everything works as expected. That said, it basically is a shameless copy from the example website included with the excellent blogdown package that I am using to set up this blog. Also, I love the pie chart below in Fig. 1.*

*The blog’s theme is Beautiful Hugo which is a port of Dean Attali’s Beautiful Jekyll theme.*

# 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.

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
fit <- lm(dist ~ speed, data = cars)
fit
##
## Call:
## lm(formula = dist ~ speed, data = cars)
##
## Coefficients:
## (Intercept) speed
## -17.579 3.932
```

# Including Plots

You can also embed plots. See Figure 1 for example:

```
par(mar = c(0, 1, 0, 1))
pie(
c(280, 60, 20),
c('Sky', 'Sunny side of pyramid', 'Shady side of pyramid'),
col = c('#2196F3', '#F7EA39', '#C4B632'),
init.angle = -50, border = NA
)
```

# Math

\(S_n = \sum_{i=1}^n X_i\)
