This is an R Markdown presentation. 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.

Install from CRAN

• install.packages(‘rmarkdown’)

• The document format “R Markdown” was first introduced in the knitr package in early 2012.
• The idea was to embed code chunks (of R or other languages) in Markdown documents.
• In fact, knitr supported several authoring languages from the beginning in addition to Markdown, including LaTeX, HTML.

• If you want to generate PDF output, you will need to install LaTeX. For R Markdown users who have not installed LaTeX before, we recommend that you install TinyTeX (https://yihui.name/tinytex/):

• install.packages(‘tinytex’)

• tinytex::install_tinytex() # install TinyTeX
