Reading Data

In blogdown the Rmd files are in the content/post folder so

data <- readRDS("../../data/mtcars.rds")
knitr::kable(head(data))

HTML Widgets

library(forecast)
library(highcharter)

hchart(forecast(AirPassengers, level = 90)) %>% 
  hc_add_theme(hc_theme_smpl())


hchart(rnorm(1000)) %>% 
  hc_add_theme(hc_theme_ft())

Tables

This is a example.

Quotes

This could be a greate quote:

Blockquotes are very handy in email to emulate reply text. This line is part of the same quote.

Quote break.

This is a very long line that will still be quoted properly when it wraps. Oh boy let’s keep writing to make sure this is long enough to actually wrap for everyone. Oh, you can put Markdown into a blockquote.

End.

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('#0292D8', '#F7EA39', '#C4B632'),
  init.angle = -50, border = NA
)
A fancy pie chart.

List

Listing things.

Sometimes you want numbered lists:

  1. One
  2. Two
  3. Three

Sometimes you want bullet points:

  • Start a line with a star
  • Profit!

Alternatively,

  • Dashes work just as well
  • And if you have sub points, put two spaces before the dash or star:
    • Like this
