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:

Markdown is technically a scripting language (really??)

italics and italics

bold and bold

superscript2

strikethrough

my Linkedin

Header 1

Header 2

Header 3

Header 4

Header 5
Header 6

endash: –

emdash: —

ellipsis: …

inline equation: \(A = \pi*r^{2}\)

image:

horizontal rule (or slide break):

block quote

  • unordered list

  • item 2
    • sub-item 1
    • sub-item 2

  1. ordered list

  2. item 2
    • sub-item 1
    • sub-item 2
Table Header Second Header
Table Cell Cell 2
Cell 3 Cell 4

Place code inline with a single back ticks. The first back tick must be followed by an R, like a=2,abd b=3 then a+b is equal to 5.

Add chunk options within braces. For example, echo=FALSE will prevent source code from being displayed, if eval=FALSE, knitr will not run the code in the code chunk:

## [1] "Hello World!"

If collapse=TRUE, knitr will collapse all the source and output blocks created by the chunk into a single block.

paste("Hello", "World!")
## [1] "Hello World!"

There are many other R code chunck options which may also be extermely helpful such as warnings. Google R Markdown Chunk option for more details

Couple of more examples from the RMarkdown default file in R studio:

str(cars)
## 'data.frame':    50 obs. of  2 variables:
##  $ speed: num  4 4 7 7 8 9 10 10 10 11 ...
##  $ dist : num  2 10 4 22 16 10 18 26 34 17 ...

You can also embed plots, for example:

Through markdown there is a functionality to create presentation embedding R code and LaTeX.

Here is one example I created for a project
